Hi All,

can anybody help me to resolve the following norm and trace minimization probelm using CVX? my matalb code as follow:

cvx_begin

variable ZZ(LI,1) complex

minimize 1/2 * square_pos(norm((P_matrix .* toeplitz(ZZ) - RRV_INTER) , ‘fro’)) +

1/4 * trace(toeplitz(ZZ))

subject to

toeplitz(ZZ) == semidefinite(LI);

cvx_end

error information as following:

error use +

Disciplined convex programming error:

Illegal operation: {convex} + {complex affine}

error minimize

x = evalin(‘caller’,sprintf(’%s’, varargin{:}))

I would appreciate it if anybody can help me to solve this problem.

Thanks

Xie
