SORTQQ

[g_f_thomas]

Why does:

use ifport

:

z =

cmplx(x,y) ! x, y, z are all double 1-D arrays of the same length call sortqq(loc(real(z)), xend, srt$real8)

:

fail? I'm merely trying to sort z wrt its real part.

Thanks,

Gerry

You're sorting a temporary expression consisting of the values from the real part of Z, and not Z itself. Once the call returns, the temporary goes away.

I don't think you can do what you want with SORTQQ. Use QSORT instead and write your own comparison function.

Gerry,

SORTQQ assumes all data are keys.

Look at using QSORT
