How to Resolve Subscript Indices Error in f2matlab Conversion?

[cre_96]

Hi!
I've got some trouble with using f2matlab.
I need to convert a f90 source code into MATLAB code.In order to do this i type on MATLAB command window:
>>f2matlab('filename.f90');
but MATLAB displays the following error:

? Subscript indices must either be real positive integers or logicals.

Error in ==> f2matlab at 130
if ~inastring_f(filestr(temp7(temp6(j)):temp7(temp6(i))),temp7(temp6(i))-temp7(temp6(j))+1)

Does anybody know how to fix it?

I would think that your i (or j) goes from 0,1,2,3,...

temp6(0), temp6(1),...

Matlab doesn't reference elements at zero.

Maybe try rewriting the fortran code so that i and j go from 1,2,3,...

temp6(1), temp6(2),... =equal the old temp6(0), temp6(1),...

(I haven't used f2matlab but would have assumed that it reassigned these calls automatically (same if I ever wanted to convert C to Matlab).)

Hi there,

It seems like you are facing an error while trying to convert a f90 source code into MATLAB code using f2matlab. The error message you received indicates that there is an issue with the indexing in your code.

One possible solution could be to check your code and make sure that all the indices used are either positive integers or logicals. It could also be helpful to check if there are any missing or incorrect parentheses or brackets in your code.

Additionally, you can try to run the code in a debugger to pinpoint the exact location of the error and troubleshoot from there.

If the issue persists, you can try reaching out to the developers of f2matlab for further assistance. They may have a better understanding of the error and how to resolve it.

I hope this helps. Good luck!
