def dtrttf(a, transr = N, uplo = U)

Summary

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

a : ndarray: Square matrix of shape (n, n); only the triangle named by uplo is read.
transr : str, optional: 'N' for the normal RFP layout, 'T' for the transposed one. Default is 'N'.
uplo : str, optional: 'U' if the matrix is upper triangular, 'L' if lower. Default is 'U'.
