Error using optimset lsqnonlin

Hi,

I have been using an older version of MATLAB with optimization toolbox but recently upgraded to MATLAB 2014b with Optimization Toolbox 7.1

However, I have a code that uses the following function call optimset('lsqnonlin');

It gives me the following error message:

No default options available for the function 'lsqnonlin'.

Can someone please help why is it function call not working?

That release knew about 'lsqnonneg' but not 'lsqnonlin'
