Error using fwrite : Cannot write value: sparse arrays are unsupported.

Is there any way to save a sparse matrix into a binary file?

I cannot convert from the sparse matrix to dense matrix because of the limitation in memory. I have to use a large sparse matrix sparse(1e5,1e5).

Thank you in advanced!

[i,j,v] = find(S);

then save i,j,v with fwrite

It works.

Thank you!
