//Multiply two 3x3 matrixs. This function developed by Jordi can be easily adapted to multiple n*n matrix's. (Pero me da flojera!). void Matrix_Multiply(float a[3][3], float b[3][3],float mat[3][3]) { float op[3]; for(int x=0; x<3; x++) { for(int y=0; y<3; y++) { for(int w=0; w<3; w++) { op[w]=a[x][w]*b[w][y]; } mat[x][y]=0; mat[x][y]=op[0]+op[1]+op[2]; float test=mat[x][y]; } } }
