scipy.linalg.lapack.dormrz_lwork

scipy.linalg.lapack.dormrz_lwork(m, n, side='L', trans='N') = <flapack function dormrz_lwork>

Query the optimal workspace for dormrz (LAPACK dormrz with lwork = -1).

Parameters:

mint

Number of rows of the matrix.

nint

Number of columns of the matrix.

sidestr, optional

'L' for Q @ c, 'R' for c @ Q. Default is 'L'.

transstr, optional

'N' to apply Q, 'T' to apply its transpose. Default is 'N'.

Returns:

workfloat

Optimal lwork.

infoint

0 on success; if negative, the -info-th argument had an illegal value.
