transpose in Fortran example

[urbanjost]

With optimization on most Fortran compilers will remove the issue, but you seem to declare a constant array and then transpose it,
and then transpose it again (returning it to the values before the first transpose) on each pass. If I am reading that correctly you can eliminate the transpose calls in the Fortran example. With optimization turn offed it might make a significant difference. With optimization on it is very likely the operations were removed from the loop and the change would be negligible.
