In gmres, there seems to be a bug, too:
Line 84: "x = x + V*y; "
but V has dimensions n and m+1 whereas y has dimension m ...?

I believe there is an error in bicgstab:

Line 61 should probably be
"if ( norm(s)/bnrm2 < tol ),"
instead of
"if ( norm(s) < tol ),"

and line 82 probably needs to be
"if ( error <= tol | norm(s)/bnrm2 <= tol ),"
instead of
"if ( error <= tol | s <= tol ),"

Please correct me if I am mistaken ...
