Is it possible to call specific C functions in matlab?

Hi there,

I want to Simulate GPS signal in Matlab and have written a code which seems to be working partially. The problem is in the premable of the data which is causing the issue during the subframe identification process. I wanted to ask if there is anyway to call and use a function that is already written in C langage.

Is it possible? can we do it? If yes can you please provide me some reference material or guidance on how to do it?

I would like to call a few functions such as GenerateNavMessage from the following link:

Thank you in advance

You have to write a mex wrapper function that calls the C code.

How easy this is will depend upon the data passing chosen in the implementation of the function -- straight numeric types can be handled pretty easily; if it uses C structures you'll have more issues to resolve.

you can use the Legacy Code tool to do exactly this. Integrate C Functions Using Legacy Code Tool - MATLAB & Simulink - MathWorks Italia
