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

Signature

def dtrtri(c, lower = 0, unitdiag = 0, overwrite_c = 0)

Summary

Invert a triangular matrix (LAPACK dtrtri).

Parameters

c : ndarray: Square triangular matrix; only the triangle named by lower is read.
lower : int, optional: If nonzero, c is lower triangular; otherwise upper. Default is 0.
unitdiag : int, optional: If nonzero, the matrix is treated as having a unit diagonal and the stored diagonal is not referenced. Default is 0.
overwrite_c : int, optional: If nonzero, c may be overwritten in place. Default is 0.

Returns

inv_c : ndarray: The inverse, overwriting c.
info : int: 0 on success; if negative, the -info-th argument had an illegal value.
