class httk.FracScalar(nom, denom)

Bases: FracVector

Represents the fractional number nom/denom. This is a subclass of FracVector with the purpose of making it clear when a scalar fracvector is needed/used.

classmethod create(nom, denom=None, simplify=True)

Create a FracScalar.

FracScalar(something)

something may be any object that can be used in the constructor of the Python Fraction class (also works with strings!).

class httk.FracVector(noms, denom=1)

Bases: Vector

FracVector is a general immutable N-dimensional vector (tensor) class for performing linear algebra with fractional numbers.

A FracVector consists of a multidimensional tuple of integer nominators, and a single shared integer denominator.

Since FracVectors are immutable, every operation on a FracVector returns a new FracVector with the result of the operation. A created FracVector never changes. Hence, they are safe to use as keys in dictionaries, to use in sets, etc.

Note: most methods returns FracVector results that are not simplified (i.e., the FracVector returned does not have the smallest possible integer denominator). To return a FracVector with the smallest possible denominator, just call FracVector.simplify() at the last step.

T()

Returns the transpose, A^T.

acos(prec=None, degrees=False, limit=False)

Return a FracVector where every element is the arccos of the element in the source FracVector.

prec = precision (should be set as a fraction) limit = True requires the denominator to be smaller or equal to precision

argmax()

Return the index of the maximum element across all dimensions in the FracVector.

argmin()

Return the index of the minimum element across all dimensions in the FracVector.

asin(prec=None, degrees=False, limit=False)

Return a FracVector where every element is the arcsin of the element in the source FracVector.

prec = precision (should be set as a fraction) limit = True requires the denominator to be smaller or equal to precision

ceil()

Returns the integer that is equal to or just below the value stored in a scalar FracVector.

classmethod chain_vecs(vecs)

Optimized chaining of FracVectors.

vecs: a list (or tuple) of fracvectors.

Returns the same thing as

FracVector.create(vecs,chain=True)

i.e., removes outermost dimension and chain the sub-sequences. If input=[[1 2 3],[4,5,6]], then

FracVector.chain(input) -> [1,2,3,4,5,6]

but this method assumes all vectors share the same denominator (it raises an exception if this is not true)

cos(prec=None, degrees=False, limit=False)

Return a FracVector where every element is the cosine of the element in the source FracVector.

prec = precision (should be set as a fraction) limit = True requires the denominator to be smaller or equal to precision

classmethod create(noms, denom=None, simplify=True, chain=False, min_accuracy=Fraction(1, 10000))

Create a FracVector from various types of sequences.

Simplest use:

FracVector.create(some_kind_of_sequence)

where ‘some_kind_of_sequence’ can be any nested list or tuple of objects that can be used in the constructor of the Python Fraction class (also works with strings!). If any object found while traveling the items has a .to_fractions() method, it will be called and is expected to return a fraction or list or tuple of fractions.

Optional parameters:

• Invocation with denominator: FracVector.create(nominators,denominator) nominators is any sequence, and denominator a common denominator to divide all nominators with

• simplify: boolean, return a FracVector with the smallest possible denominator.

• chain: boolean, remove outermost dimension and chain the sub-sequences. I.e., if input=[[1 2 3],[4,5,6]], then FracVector.create(input) -> [1,2,3,4,5,6]

Relevant: FracVector itself implements .to_fractions(), and hence, the same constructor allows stacking several FracVector objects like this:

vertical_fracvector = FracVector.create([[fracvector1],[fracvector2]])
horizontal_fracvector = FracVector.create([fracvector1,fracvector2],chain=True)

• min_accuracy: set to a boolean to adjust the minimum accuracy assumed in string input. The default is 1/10000, i.e. 0.33 = 0.3300 = 33/100, whereas 0.3333 = 1/3. Set it to None to assume infinite accuracy, i.e., convert exactly whatever string is given (unless a standard deviation is given as a parenthesis after the string.)

classmethod create_cos(data, degrees=False, limit=False, find_best_rational=True, prec=Fraction(1, 1000000))

Creating a FracVector as the cosine of the argument data. If data are composed by strings, the standard deviation of the numbers are taken into account, and the best possible fractional approximation to the cosines of the data are returned within the standard deviation.

This is not the same as FracVector.create(data).cos(), which creates the best possible fractional approximations of data and then takes cos on that.

classmethod create_exp(data, prec=Fraction(1, 1000000), limit=False)

Creating a FracVector as the exponent of the argument data. If data are composed by strings, the standard deviation of the numbers are taken into account, and the best possible fractional approximation to the cosines of the data are returned within the standard deviation.

This is not the same as FracVector.create(data).exp(), which creates the best possible fractional approximations of data and then takes exp on that.

classmethod create_sin(data, degrees=False, limit=False, prec=Fraction(1, 1000000))

Creating a FracVector as the sine of the argument data. If data are composed by strings, the standard deviation of the numbers are taken into account, and the best possible fractional approximation to the cosines of the data are returned within the standard deviation.

This is not the same as FracVector.create(data).sin(), which creates the best possible fractional approximations of data and then takes cos on that.

cross(other)

Returns the vector cross product of the 3-element 1D vector with the 3-element 1D vector ‘other’, i.e., A x B.

det()

Returns the determinant of the FracVector as a scalar FracVector.

property dim

This property returns a tuple with the dimensionality of each dimension of the FracVector (the noms are assumed to be a nested list of rectangular shape).

dot(other)

Returns the vector dot product of the 1D vector with the 1D vector ‘other’, i.e., A . B or A cdot B. The same as A * B.T().

exp(prec=None, limit=False)

Return a FracVector where every element is the exponent of the element in the source FracVector.

prec = precision (should be set as a fraction) limit = True requires the denominator to be smaller or equal to precision

classmethod eye(dims)

Create a diagonal one-matrix with the given dimensions

flatten()

Returns a FracVector that has been flattened out to a single rowvector

floor()

Returns the integer that is equal to or just below the value stored in a scalar FracVector.

classmethod from_floats(l, resolution=4294967296)

lengthsqr()

Returns the square of the length of the vector. The same as A * A.T()

limit_denominator(max_denom=1000000000)

Returns a FracVector of reduced resolution.

resolution: each element in the returned FracVector is the closest numerical approximation that can is allowed by a fraction with maximally this denominator. Note: since all elements must be put on a common denominator, the result may have a larger denominator than max_denom

max()

Return the maximum element across all dimensions in the FracVector. max(fracvector) works for a 1D vector.

metric_product(vecA, vecB)

Returns the result of the metric product using the present square FracVector as the metric matrix. The same as

vecA*self*vecB.T().

min()

Return the minimum element across all dimensions in the FracVector. max(fracvector) works for a 1D vector.

mul(other)

Returns the result of multiplying the vector with ‘other’ using matrix multiplication.

Note that for two 1D FracVectors, A.dot(B) is not the same as A.mul(B), but rather: A.mul(B.T()).

nargmax()

Return a list of indices of all maximum elements across all dimensions in the FracVector.

nargmin()

Return a list of indices for all minimum elements across all dimensions in the FracVector.

static nested_map(op, *ls)

Map an operator over a nested tuple. (i.e., the same as the built-in map(), but works recursively on a nested tuple)

set_denominator(set_denom=1000000000)

Returns a FracVector of reduced resolution where every element is the closest numerical approximation using this denominator.

sign()

Returns the sign of the scalar FracVector: -1, 0 or 1.

Return a FracVector where every element is the sine of the element in the source FracVector.

prec = precision (should be set as a fraction) limit = True requires the denominator to be smaller or equal to precision

and, e.g.,

mfracvec[:,7] = [1,2,3,4]

Other than this, the FracVector methods exist and do the same, i.e., they return copies of the fracvector, rather than modifying it.

However, methods have also been added named with set_* prefixes which performs mutating operations, e.g.,

A.set_T()

replaces A with its own transpose, whereas

A.T()

just returns a new MutableFracVector that is the transpose of A, leaving A unmodified.
