How to solve the problem: {convex} .* {convex}

1

My code is as follows,
cvx_begin
variable R(para.M,para.M) complex
variable x(para.M,1) complex
expression t1
expression t3
expression t4

         minimize(t1+t3+t4)
       
          subject to          
          
                t1=(para.sigma_z+(square_pos(norm(H_SI*x))))*inv_pos((2*30*(real(trace(A1_left*R*A1_left')))));
            
                t3=(para.sigma_z+(square_pos(norm(H_SI*x))))*inv_pos((2*30*(real(trace(A1*R*A1')))));
            
                t4=(para.sigma_z+(square_pos(norm(H_SI*x))))*inv_pos((2*30*(real(trace(A1_right*R*A1_right')))));
                
                norm(R-R1)<=0.05;
                [R   x;...
                        x'  1]==hermitian_semidefinite(para.M+1);   
                   for k=1:(para.K)
                       h=H(:,k);                             
                       real(h'*x*s)*sin(pi/para.omiga) - abs( imag(h'*x*s) )*cos(pi/para.omiga) >= belta;
                      for t1=1:para.M
                        abs(x(t1))<=sqrt(Pt1(e)/para.M);
                      end
                   end
    cvx_end

and the expression is1

Can you help me to solve this problem?Thank you!

The CVX wrong is
错误使用 .* (line 173)
Disciplined convex programming error:
Cannot perform the operation: {convex} .* {convex}

出错 * (line 36)
z = feval( oper, x, y );

出错 main1 (line 107)
t1=(para.sigma_z+(square_pos(norm(H_SIx))))inv_pos((230(real(trace(A1_leftRA1_left’)))));

Have you proven this optimization problem is convex?
