3/6/2024 0 Comments Sparse matrix matlabSparse matrices are those matrices that have the majority of their elements equal to zero. Reduce computation time by eliminating operations on zero elements. The sparse attribute allows MATLAB to: Store only the nonzero elements of the matrix, together with their indices. 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.
