The stdvector template class is much more frequently utilised because it is more general. C is an object oriented language and some concepts may be new. I took this code also from this forum as a basis and changed some stuff around.

The most appropriate choices here are stdvalarray and stdvector. Multiply Rotate RotateAt Scale Shear and Translate. To do so we are taking input from the user for row number column number first matrix elements and second matrix elements.

The following example creates the matrix of a composite transformation that first rotates 30 degrees then scales by a factor of 2 in the y direction and then translates 5 units in the x direction. The result after performing the operation Matrix A Matrix B ist still Matrix A. The documentation here is slight but it is clear and well organized.
