That you for your answer, both showing what I want to do with different methods. salgerman, you understood my problem welle, I wanted to take on any one-dimensional function. I am just surprised I get a segmentation fault if I do not declare f2 and f5 as allocatables. Anyway, by declaring them...

Comparisons in 'if' statements are made with '==', because '=' is used for assignments. Moreover, when comparing characters, the characters you are comparing to need to be given between quotes (''). The following example works with my computer (gfortran) : program main implicit none...

Thank you for your help. I am going to look at those links and post my answer with, I hope, the solution as soon as possible.

Thank you, this is exactly what I was looking for ! I tried with my own example and it works very well. One last question : to avoid the use of the function overloading with the general interface, I was wondering if it was possible to define, in the interface for the function passed as argument...

You links seem to contain interesting information. I will look at them with great attention and come back later to tell if it works for my case. Thank you !

Thank you for your answers. Here are my comments to all of your recommendations. to Salgerman (post #1): The problem is that I do not to point at a variable, but at a function. Therefore, I cannot declare my pointer with real*8, pointer :: ap(:) What I tried to do is to use the following...

Hello everybody, I am starting this thread because I encounter a problem with the pointers in Fortran. I want to use a pointer of an array-valued function, but I get a segmentation fault error during execution (compilation is ok with gfortran). Everything works well when the pointer aims at a...
