Optimization Error: How do I set the algorithm of used by a function?

e.g. (R2011a) if I am using 'fmincon', I used options:

   options = optimoptions('fmincon','Display','iter','Algorithm','sqp');

I am getting an error:

Undefined function 'optimoptions' for input arguments of type 'char'.

Try this:

options=optimset('fmincon');
options.Display='iter';
options.Algorithm='sqp';
