scipy.optimize.LbfgsInvHessProduct.rmatmat

LbfgsInvHessProduct.rmatmat(self, X)[source]

Adjoint matrix-matrix multiplication.

Performs the operation y = A^H * x where A is an MxN linear operator and x is a column vector or 1-d array, or 2-d array. The default implementation defers to the adjoint.

Parameters
X{matrix, ndarray}

A matrix or 2D array.

Returns
Y{matrix, ndarray}

A matrix or 2D array depending on the type of the input.

Notes

This rmatmat wraps the user-specified rmatmat routine.
