scipy.linalg.lapack.dtfttp

scipy.linalg.lapack.dtfttp(n, arf, transr='N', uplo='U') = <flapack function dtfttp>

Convert a triangle from rectangular full packed (RFP) to packed (TP) storage (LAPACK dtfttp).

Parameters:

nint

Order of the square matrix.

arfndarray

The triangle in rectangular full packed storage (RFP), length n * (n + 1) / 2.

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:

apndarray

The triangle in packed storage (TP).

infoint

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