scipy.linalg.lapack.zheevd_lwork

scipy.linalg.lapack.zheevd_lwork(n, compute_v=1, lower=0) = <flapack function zheevd_lwork>

Query the optimal workspace sizes for zheevd.

Parameters:

nint

Order of the square matrix.

compute_vint, optional

If nonzero, eigenvectors are computed as well as eigenvalues. Default is 1.

lowerint, optional

If nonzero, the lower triangle of a is referenced; otherwise the upper. Default is 0.

Returns:

workcomplex

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

iworkint

Optimal size of the integer workspace, to pass as liwork.

rworkfloat

Optimal size of the real workspace, to pass as lrwork. The real flavors have no such output, so they return one value fewer.

infoint

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