Hello
Is there a matrix 4x4 C library. I need a one with a C interface. Only this little library not a complete framework. Something like the intel SIMD 4x4 Matrix class for C not C++.
tnx
Marco

Intel has heaps of SSE/SSE2 matrix code in C, with sprinkles of assembly tossed in for good measure.
I have my own library that is also public.
It contains some functions for matrix multiplications, tranforming vertices, the usual matrix operations
glhUnProjectf
glhProjectf
glhInvertMatrixfv_2
glhQuickInvertMatrixfv_2
glhMultiplyMatrixByMatrix4by4f_2
glhMultiplyMatrixByVector4by4f_SSE_Aligned_1
The entire Block 12 in the header file...

an open source GLU replacement library. Much more modern than GLU.
float matrix[16], inverse_matrix[16];
glhLoadIdentityf2(matrix);
glhTranslatef2(matrix, 0.0, 0.0, 5.0);
glhRotateAboutXf2(matrix, angleInRadians);
glhScalef2(matrix, 1.0, 1.0, -1.0);
glhQuickInvertMatrixf2(matrix, inverse_matrix);
glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);
