scipy.linalg.lapack.cgesdd_lwork

scipy.linalg.lapack.cgesdd_lwork(m, n, compute_uv=1, full_matrices=1) = <flapack function cgesdd_lwork>

Query the optimal lwork for cgesdd.

Parameters:

mint

Number of rows of the matrix.

nint

Number of columns of the matrix.

compute_uvint, optional

If nonzero, singular vectors are computed. Default is 1.

full_matricesint, optional

If nonzero, full-sized u and vt are computed. Default is 1.

Returns:

workcomplex

Optimal size of the work array, as a scalar of the routine’s dtype.

infoint

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