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.
