function [A, Z] = mread (filename,prefer_binary) %#ok
%MREAD read a sparse matrix from a file in Matrix Market format.
%
% Example:
% A = mread (filename)
% [A Z] = mread (filename, prefer_binary)
%
% Unlike MMREAD, only the matrix is returned; the file format is not
% returned. Explicit zero entries can be present in the file; these are not
% included in A. They appear as the nonzero pattern of the binary matrix Z.
%
% If prefer_binary is not present, or zero, a symmetric pattern-only matrix
% is returned with A(i,i) = 1+length(find(A(:,i))) if it is present in the
% pattern, and A(i,j) = -1 for off-diagonal entries. If you want the original
% Matrix Market matrix in this case, simply use A = mread (filename,1).
