Why do I receive an error when I pass a lambda value for the 'levenberg-marquardt' algorithm using OPTIMOPTIONS, in MATLAB 8.1 (R2013a) ?

When I am executing the following command according to the documentation :

lsqoptions = optimoptions(@lsqnonlin,'Algorithm',{'levenberg-marquardt',.005});

I receive the following error :

 Error using optimoptions (line 114)

 Too many outputs requested.  Most likely cause is missing [] around left hand side that has a comma separated list expansion.

This is a bug in MATLAB 8.1 (R2013a) in the way optimoptions takes the inputs.

As a workaround you can use OPTIMSET :

lsqoptions = optimset('Algorithm',{'levenberg-marquardt',.005});
