scipy.linalg.lapack.strttf

scipy.linalg.lapack.strttf(a, transr='N', uplo='U') = <flapack function strttf>

Convert a triangle from full (TR) to rectangular full packed (RFP) storage (LAPACK strttf).

Parameters:

andarray

Square matrix of shape (n, n); only the triangle named by uplo is read.

transrstr, optional

'N' for the normal RFP layout, 'T' for the transposed one. Default is 'N'.

uplostr, optional

'U' if the matrix is upper triangular, 'L' if lower. Default is 'U'.

Returns:

arfndarray

The triangle in rectangular full packed storage (RFP).

infoint

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