Sparse is an attribute that you can assign to any two-dimensional MATLAB® matrix that is composed of double or logical elements. S = sparse( m,n ) generates an m -by- n all zero sparse matrix.īout = spdiags( A ) extracts the nonzero diagonals from m -by- n matrix A and returns them as the columns in min(m,n) -by- p matrix Bout, where p is the number of nonzero diagonals. If a matrix contains many zeros, converting the matrix to sparse storage saves memory. S = sparse( A ) converts a full matrix into sparse form by squeezing out any zero elements.
