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 memory stored as a full block diagonal matrix.Operations B'*M = (M'*B)' and M*B' can be performed using transpose identities

Requirements: No special requirements
