nimble.calculate.inverse

nimble.calculate.inverse(aObj)

Compute the (multiplicative) inverse of a nimble Base object.

Parameters:

aObj (nimble Base object.) – Square object to be inverted.

Returns:

aInv (nimble Base object.) – Inverse of the object aObj

Raises:

• InvalidArgumentType – If aObj is not a nimble Base Object. If aObj elements types are not supported.

• InvalidArgumentValue – If aObj is not square. If aObj is not invertible (Singular).

Examples

>>> lst = [[1, 2], [3, 4]]
>>> X = nimble.data(lst)
>>> X
