What does 'rfac' do in Fortran?

[mushi]

Hi guys,

I know I may sound stupid to me many of you but can anybody tell me what does 'rfac' do in Fortran.

I don't understand your question. Can you provide some context?

Actually I am working on a code that has been written by someone else and I found 'rfac(X)' in that code. The code is written in Fortran and I am trying to use it in Matlab. I have checked everywhere but could not find any function named 'rfac'.

I hope I am clear now.

my guess is it's a locally defined variable or function.

a google search on 'rfac fortran' turns up lots of incidences but in ones i found it was defined in the code.
maybe something passed to a sub?

can you do text search on the program?

have you done a text search for rfac in all your fortran sources? I usually work on Linux and a 'grep' for a given function or variable name returns all the places where is being used...you can gain a lot of insight very quickly by viewing all the usage for a given variable/function.
