分布式下/上三角矩阵的上/下部分的原位恢复

I wonder if there exists any Scalapack routine that may convert a triangular matrix back to a general one, i.e. copies the lower/upper part to the upper/lower part - I couldn't find it yet. I know there exists an easy workaraound using p?geadd with manipulation of the diagonal, but that one consumes twice as much memory as theoretically needed and I can't afford that... So it seems strange to me, that Scalapack/PBLAS doesn't provide any routine solving this relative simple problem. If anybody knows more than I please let me know!I wonder if there exists any Scalapack routine
