covmats.CovViaSparseCholesky.rmatvec

CovViaSparseCholesky.rmatvec(x)

Adjoint matrix-vector 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.

Parameters:

x ({matrix, ndarray}) – An array with shape (M,) or (M,1).

Returns:

y – A matrix or ndarray with shape (N,) or (N,1) depending on the type and shape of the x argument.

Return type:

{matrix, ndarray}

Notes

This rmatvec wraps the user-specified rmatvec routine or overridden _rmatvec method to ensure that y has the correct shape and type.
