source: build-install/usr/lib/python3.14/site-packages/scipy/linalg/_flapack.cpython-314-x86_64-linux-gnu.so

Signature

def zgelsy_lwork(m, n, nrhs, cond, lwork = -1)

Summary

Query the optimal lwork for zgelsy.

Parameters

m : int: Number of rows of the matrix.
n : int: Number of columns of the matrix.
nrhs : int: Number of right-hand sides.
cond : float, optional: Singular values below cond times the largest are treated as zero. Default is -1.0, which uses machine precision.
lwork : int, optional: Passed through to LAPACK; -1 requests the query. Default is -1.

Returns

work : complex: Optimal size of the work array, as a scalar of the routine's dtype.
info : int: 0 on success; if negative, the -info-th argument had an illegal value.
