MatStack (Function) In french: MatCompresse Compresses the memory footprint occupied by a matrix. Remark: The compression is required when you handle a large matrix onto which several calculations have been made. If the matrix contains several null columns and/or rows, compression can significantly reduce the matrix memory size.
