block diagonal multiplication Used to perform B*M or M*B with B a block diagonal matrix, B is stored as a cell array (call it C) with each element a matrix as a block of B, such that B = blkdiag(C{:}).This speeds up the multiplication when B is large and also allows the operation to take place when B could not fit in the...

Anti-diagonal matrix traversal This function takes as an input a square matrix and returns two outputs. The first is a vector containing the matrix values starting in the (1,1) entry and progressing along the anti-diagonal elements. A second output gives the sum of the elements along the anti-diagonals.For example:a = [1 2 3;... Platforms: Matlab
