HI Dear ALL,

Could anybody be kindly enough to give me an instruction to solve this
2D poisson equation using Fortran language:

Δ(φ)=R-x^2-y^2

Any comments will be greatly appreciated. Thanks.

Hi guys,

I have a simple question to ask.

In fortran90, I define a 2by2 matrix, for example, real(8):: mat(2,2).
Then I want to assign value to this matrix. But when I use mat=(/
1,2,3,4 /), it says "Error: The shapes of the array expressions do not
conform." Do you know how should I modify it? Thanks a lot.

Hello,

how can I incorporate an .inc-file (from the HDF library) which is
written in F77 in an F90 file.
I tried it with

include filename.inc

but always get some error messages because it is not identified as a
Fortran file.

Thanks for your help in advance !
