Dear all,
Please am working on a project and now found a FORTRAN code to speed up my research but I having been using MATLAB and so, I need to convert the newly found FORTRAN code to MATLAB. Please kindly help me out on this conversion or give a detail explanation on how best I can convert from FORTRAN to MATLAB. The FORTRAN code is in the attachment. Thanks in anticipation!

Options:
1. Convert the FORTRAN code to MATLAB line by line going through the code.
2. If problem is known, try knowing the inbuilt functions, toolboxes in MATLAB.

I don't think you can automatically convert your FORTRAN code to MATLAB; however, you can compile it as mex file and use it in MATLAB.

My f2matlab can do this kind of conversion. Please download from the file exchange and give it a try. You will have to split the code up into the five files in the pdf and run f2matlab on each file.
I might also do a free conversion if I get time, but in any case, if you run into trouble PM me.

HI Ben Barrowes, Thank you so much for responding so kindly to my question. I'm just starting to study this topic and some questions arose that I could not solve on my own from the instructions you suggested. With your permission, I will later send questions in a personal mail that I have not resolved, after I try to solve it myself.

Understood. Good luck Rob.
