[Scalapack] blacs_pcoord


Hello,
no no

The documentation is correct. For blacs_pcoord:

PROW
     (output) INTEGER.
     On output, the row coordinate of process PNUM in the BLACS grid.
PCOL
     (output) INTEGER.
     On output, the column coordinate of process PNUM in the BLACS grid.

Maybe test out the program 'Hello World' at:
http://www.netlib.org/blacs/BLACS/Examples.html

It basically checks in a few lines blacs_pcoord

Hello,


I find an error in blacs_pcoord( icntxt, pnum, prow, pcol ).
The real result is:
   prow is the columns number of pnum in the grid
   pcol is the row number of pnum in the grid
