`scipy.linalg._flapack:cuncsd_lwork`

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

Signature

def cuncsd_lwork(m, p, q)

Summary

Query the workspace cuncsd needs (LAPACK cuncsd with lwork = -1).

Extended Summary

The query runs with every factor requested, no transpose and the default sign convention, which is what the .pyf hard-codes.

Parameters

m : int: Order of the partitioned matrix.
p : int: Row count of the leading block.
q : int: Column count of the leading block.

Returns

work : complex: Optimal lwork.
rwork : float: Optimal lrwork. The real flavors have no second workspace and do not return it.
info : int: 0 on success; if negative, the -info-th argument had an illegal value.
