UpsilonT=zeros(n_u*Np,n_y*Np); Gamma=zeros(n_y*Np,n); H = zeros(6,6); W_inv = zeros(6,6); lSTE = zeros(6,3);
% %%%%%%%%%%%%%%%%%%%%%% System Matrixce%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Yref = [iq_ref; id_ref; wm;0];
%Vo_xy_ref = [real(vref) imag(vref) wm]';
%% System state
x_k = zeros(3);
id = real(is_meas);
iq = imag(is_meas);
x_k = [id; iq; wm ];
uabc_k_1 = [0 0 0]';
% %% Unconstrained solution calculation
F_k=UpsilonT*(Gamma*x_k-Yref)-lSTE*uabc_k_1;

I have already defined my matrices even the x_k just to be safe but

Error:Expected either a logical, char, int, fi, single, or double. Found an mxArray. MxArrays are returned from calls to the MATLAB interpreter and are not supported inside expressions. They may only be used on the right-hand side of assignments and as arguments to extrinsic functions.
