Freeware Listing: Matrices

This function makes an imagesc-like plot for two matrices with equal dimensions, in which each each cell of the plot is split diagonally with the upper triangle of cell (i,j) in the plot representing the Matrix1(i,j) and the lower triangle representing Matrix2(i,j)..

A set of blocks for manipulating 3x3 and 4x4 matrices. In versions of Simulink prior to R12, matrices were handled in row-major form, thus the need for special blocks to handle matrices. Although Simulink can now handle arrays as signals, some users may still find the row-major approach useful. There are two MATLAB functions provided to help manipulate the inputs and outputs of any Simulink model that uses the Matrix Library. These are: rm2mat - row major form to an array of 2-dim matrices mat2rm - array of 2-dim matrices to row major form.
