I get the following error , can anyone help?

??? Error using ==> subsindex
Function ‘subsindex’ is not defined for values of class

Error in ==> cvx_end at 130
evalin( ‘caller’, ‘pop( cvx_problem, ‘‘value’’ )’ );

Never seen this one. You should probably submit a support request to http://support.cvxr.com with your full cvx_setup output, and code that reproduces the error.
