Utils¶

Collection of utilities.

msinvar.utils.isiterable(i)[source]¶

msinvar.utils.cache(function)[source]¶

class msinvar.utils.vec[source]¶

Bases: object

static le(a, b)[source]¶

static iszero(a)[source]¶

static zero(a)¶

static equal(a, b)[source]¶

static vmin(a, b)[source]¶

static vmax(a, b)[source]¶

static scal(c, v)[source]¶

static dot(a, b)[source]¶

static sub(a, b)[source]¶

static add(a, b=None)[source]¶: Return the sum of vectors a, b. If b=None, return the sum of vectors in the list a.

static basis(i, n)[source]¶: Return the standard i-th basis vector of dimension n. Here 0<=i<n.

msinvar.utils.info(f)[source]¶

msinvar.utils.disp(G)[source]¶

msinvar.utils.timer(f, n=1000)[source]¶

msinvar.utils.set_plots()[source]¶

msinvar.utils.phi(q, n)[source]¶

Return \((q)_n=\prod_{i=1}^n(1-q^i)\).

If n is a list, apply phi() to all entries and take the product.

msinvar.utils.poch(a, q, n)[source]¶

Return the Pochhammer symbol \((a;q)_n=\prod_{i=0}^{n-1}(1-aq^i)\).

If n is a list, apply poch() to all entries and take the product.
