How to do transpose for trtrs (or tptrs) in blas?
I want to solve:
XA = B
But it seems that trtrs only lets me solve:
AX = B
Or, using the 'transpose' flag, in trtrs:
A'X = B
which, rearranging is:
(A'X)' = B' X'A = B'
So, I can use it to solve XA = B, but I have to first transpose B manually myself, and then, again, transpose the answer. Am I missing some trick to avoid having to do the two manual transposes?
Note that I've read through solve $xA=b$ for $x$ using LAPACK and BLAS , but it doesn't seem to explain how to avoid the two manual transposes, as far as I can tell? Or maybe I'm missing something somehow?
