error：
Undefined matrix structure type: q(3)
Trying to declare multiple variables? Use the VARIABLES keyword instead.
%*****************************code follows
cvx_begin
variable Cc_a q(3)
maximize(-Cc_a);
subject to
Cc_a>=log(1+norm(Lp0)^(2)/ (norm(Lp1)^(2)+norm(Lp2)^(2)+rnorm(q0-ue)^(2) ))-(norm(Lp0)^(2))(-(q0-ue)’(q0-ue)+2(q0-ue)’(q-ue)-norm(q0-ue)^(2))/(norm(Lp0)^(2)+norm(Lp1)^(2)+norm(Lp2)^(2)+rnorm(q0-ue)^(2))/(norm(Lp1)^(2)+norm(Lp2)^(2)+rnorm(q0-ue)^(2) );
q<=qmax;
q>=qmin;
cvx_end
Do what the error message says:
variables Cc_a q(3)

As flexible as the variable statement may be, it can only be used to declare a single variable, which can be inconvenient if you have a lot of variables to declare. For this reason, the variables statement is provided which allows you to declare multiple variables; i.e.,
variables x1 x2 x3 y1(10) y2(10,10,10);
The one limitation of the variables command is that it cannot declare complex, integer, or structured variables. These must be declared one at a time, using the singular variable command.

I just showed you what to do, and provided the relevant extract from the CVX Users’ Guide.
This problem has been bothering me for two days, but it has finally been solved. Thank you very much for solving my confusion.
