Minimize || A x - b||_1

I’m trying to minimize || A x - b ||_1. When I do this with

nrm=1;
minimize( norm(A*x-b,nrm) );

I get the error

Function ‘subsindex’ is not defined for values of class ‘struct’.

When I set nrm=2, nothing goes wrong. This was working fine in an older version. Does anyone out there know what I need to do?

Thanks,

Can you provide your complete MATLAB and CVX code, as if starting off in a new MATLAB session?

Also provide the output from
cvx_version
