finesse.cmatrix.KLUMatrix.zgemv

KLUMatrix.zgemv(self, double complex[::1] out, unsigned int rhs_index=0) → void

Multiply this matrix with the rhs vector corresponding to rhs_index, and store the result in out.

Performs the operation \(y = A x\).

Parameters:

outcomplex_t[::1]

The vector to store the result in.

rhs_indexunsigned, optional

The rhs vector to multiply this matrix with; defaults to 0.
