Maximum Iterations exceeded

I'm currently using optimization toolbox quadprog function and i get exitflag values of 0 which means max iter exceeded.

I tried: options = optimset('Display', 'off','LargeScale', 'off','MaxIter','500');

but i get the following error:Invalid value for OPTIONS parameter MaxIter: must be a real non-negative integer (not a string).

how can i increase maximum iterations? thanks for your help.

options = optimset('Display', 'off','LargeScale', 'off','MaxIter',500);

Just like it says: it must be a real non-negative integer, not a string.
