faster version of anint() Hi, all I have heard that the build-in function anint of fortran is kind of slow, but I have to used it quite frequent in my code. Anyone know a more efficient version of it? Thanks a lot. ... 9 Jul 2008 11:38
brothers and sisters must register and send this article to users http://www.youtube.com/watch/v/as_b6...&feature=email Lecturer: Bro Sheikh Feiz 4rm Austrailia For how long, for how long are we going to be heedless of the signs of Allah (SWT), for how long are we going to be busy with the Dunya (World), busy making money, chasing our dreams, following our desires?

Read the fortran unformatted binary data. Hi all, Hi all, Sorry for bother again, this time, I attach the fortran binary data file I want to read use the fortran code. I've a unformatted binary file named Si.cst_esp which include the data as follows if these data have been read out into a regular format file: --------------- 1 1 1... 21 Jul 2008 13:04
rlft3.f (3D Fast Fourier transform subroutine)??? Dear all; I'm going to use rlft3.f (3D Fast Fourier transform subroutine in Numerical Recipes book ) I have constructed a 107*107*107 mesh for data. I should call rlft3(data,speg,nn1,nn2,nn3,isign). ----------------------------------------------------------------------------- SUBROUTINE rlft3(data,speq,nn... 7 Jul 2008 01:15

Public review - the g0 edit descriptor The g0 edit descriptor According to the draft document: C1007 (R1006) For the G edit descriptor, d shall be specified if and only if w is not zero. To me this eliminates any value the g0 feature might have. What's needed is something like list-directed output but with the precision controlled by the ... 19 Jul 2008 03:46
Public review - Submodules Submodules I understand that when something is issued as a TR it's basically already a part of the standard even though it never went through a public review. However it was the submodule feature that convinced me that public review is just as important for TRs as for whole revised standards. The submodule f... 20 Jul 2008 00:14
Public review - Impure elementals IMPURE ELEMENTALs I don't see the value in having IMPURE ELEMENTAL procedures. There are no examples in the draft standard and the only example in the document describing new features can be rewritten without the procedure being ELEMENTAL at all. The example in the document is: impure elemental function ac... 5 Jul 2008 03:21
Public review - CRITICAL and BLOCK CRITICAL and BLOCK I won't be commenting on most of the CO-ARRAY features because I don't quite yet fully understand them. But in most of the different kinds of parallel computing I've done in the past the need for critical sections arises. Instead of a CRITICAL construct, I think that CRITICAL should be a k... 5 Jul 2008 03:21
Public review - LEADZ and TRAILZ LEADZ and TRAILZ The intrinsic functions LEADZ and TRAILZ should be called LEFTZ and RIGHTZ resprectively. It's true that if you look far enough you can find uses of "lead" and "trail" that conform to the meaning you intend in the present proposed document. However, you don't have to look far afield to find ... 18 Jul 2008 20:37 |
