1function space = spaceperc(A, k)
2% given matrix A and top number k of eigenvalues
3% difference in size of A mxn and SVD U,S,V top k in percentage is given
4% size U=mxm (mxk), S=mxn (diag k), V=nxn (nxk)
5 [m, n] = size(A);
6 storA = m * n;
7 storAk = (m * k) + k + (n * k);
8 space = storAk * 100 / storA;
