rotate.matrix[0][0] = cos + x * x * C; rotate.matrix[0][1] = x * y * C - z * sin; rotate.matrix[0][2] = x * z * C + y * sin; rotate.matrix[0][3] = 0; rotate.matrix[1 ...
In this page, we introduce a differential based method for vector and matrix derivatives (matrix calculus), which only needs a few simple rules to derive most matrix derivatives. This method is useful ...
