How to do transpose for trtrs (or tptrs) in blas?I want to solve:XA = BBut it seems that trtrs only lets me solve:AX = BOr, using the 'transpose' flag, in trtrs:A'X = Bwhich, 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?

Since basically all that xTRTRS does is call xTRSM (from BLAS), why not just call that directly? xTRSM contains a SIDE parameter which lets you specify exactly what you want.
