Hello, I am trying to open a mat file in C. My matfile contains only a matrix called "X(1,1:1024)".
I found the following code to open a mat file in C:
#include "mat.h"
MATFile *matOpen(const char *filename, const char *mode);
However, I am not able to find the file "mat.h" in the internet. Is there another way to load the data into the C program?
Thank you in advance!

Yes, I have installed Matlab. I only found a header file called "math.h"

The file is included with MATLAB installation. You might have to add it to the path where your compiler looks for header files.

In particular it is in the MATLAB installation directory as extern/include/mat.h
On my system, if I were using a command line compiler, that would involve adding the option
-I/Applications/MATLAB_R2020b.app/extern/include
The -I option for (most) compilers names a top-level directory to look in to resolve #include statements.
