Remarks

To retrieve a value from a matrix, use the GetElement function above. The parameters for the GetElement function use the format GetElement(columnIndex, rowIndex).

cMatrixf m1(cVector4f(0, 1, 2, 3), 
            cVector4f(4, 5, 6, 7), 
	    cVector4f(8, 9, 10, 11), 
	    cVector4f(12, 13, 14, 15));

float f = m1.GetElement(1, 2);

'' value of f: 9

To do matrix computations, use the cMath_MatrixXXX family of functions.

cMatrixf m1(cVector4f(1, 1, 1, 1), 
            cVector4f(2, 2, 2, 2), 
            cVector4f(3, 3, 3, 3), 
            cVector4f(4, 4, 4, 4));

cMatrixf m2(cVector4f(5, 5, 5, 5), 
            cVector4f(6, 6, 6, 6), 
            cVector4f(7, 7, 7, 7), 
            cVector4f(8, 8, 8, 8));
            
cMatrixf m3 = cMath_MatrixMul(m1, m2);

// value of m3: { 26,  26,  26,  26,
//                52,  52,  52,  52,
//                78,  78,  78,  78,
''                104, 104, 104, 104 }
