keeping T constant we have to minimize Q. How to code.

c1,c2 matrices NxN

X matrix Lx1 here L=4 . A order NxL a1 order 1xN

```
cvx_begin
variable x(4)
variable k
T=a1*c1*A*x;
Q=a1*c2*A*x;
minimize((Q))
subject to
T is constant
x(1)==k;
x(2)==0;
x(4)==0;
sum(x(1:3))==0.5*k;
A*x>0;
cvx_end
```

T is constant giving error.
