inverse

inverse(matrix: MatrixBase) → MutableDenseMatrix

Invert a symbolic matrix 2x2 or 3x3 matrix. This method is faster than the corresponding sympy method.

Examples

>>> m22 = sy.MatrixSymbol('m', 2, 2).as_explicit()
>>> inverse(m22) == m22.inv(method='ADJ')
True

>>> m33 = sy.MatrixSymbol('m', 3, 3).as_explicit()
>>> inverse(m33) == m33.inv(method='ADJ')
True

Parameters:

matrix – SymPy matrix of shape (3, 3) or (2, 2)

Returns:

inverted SymPy matrix of shape (3, 3) or (2, 2)
