Square Matrices

Computer graphics uses square matrices for many purposes. Most transformations, such as changing the point of view in a 3D world or projecting it into a 2D image, are done with square matrices.

Square matrices have properties that are not in general shared by other rectangular matrices. To get a taste of one of these properties, perform the following multiplication:

A				I				=	C

Try changing some of the elements of A (don't change elements of I) and try the product again. Only integer elements will work in this demonstration.
