Ubuntu :: Error: Matrix.h: No Such File Or Directory

I use Codeblocks as IDE environment for my C programs. I recently added the matrix library Meschach, but unfortunately the headers are not found during compiling/linking process.For instance, my generic program is the one below:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <matrix.h>

[code]...

This program generates the following error during compilation:

Quote:

main.c|3|error: matrix.h: No such file or directory|

And the declaration <matrix.h> is supposed to include the Meschach library, according to the instruction on the below link:

Furthermore, I see on folder /usr/include the following:File stdio.h;
Filestdlib.h;
Folder "Meschach", which contains the file "matrix.h".
