function s = spalloc(m,n,nzmax)
%SPALLOC Allocate space for sparse matrix.
%   S = SPALLOC(M,N,NZMAX) creates an M-by-N all zero sparse matrix
%   with room to eventually hold NZMAX nonzeros.
%
%   For example
%       s = spalloc(n,n,3*n);
%       for j = 1:n
%           s(:,j) = (a sparse column vector with 3 nonzero entries);
%       end
