**I have installed SCS solver and combiled it. Then, I installed CVX 3.0b. The SCS solver now exists in the list of solvers.
I run this problem using SeDuMi and it gets solved**

cvx_solver SeDuMi

N=10;

a=randn(N,1);

b=randn(N,1);

A=a*a’;

B=b*b’;

cvx_begin

variable X(N,N) complex semidefinite

maximize( log(trace(A*X))-trace(B*X) )

subject to

trace(X)==1

X == hermitian_semidefinite(N)

cvx_end

**However, when I change the solver to SCS (cvx_solver SCS), I get the following error**

Calling SCS 1.0: 424 variables, 103

equality constraints

------------------------------------------------------------ Status: Error Optimal value

Reference to non-existent field ‘prec’.

**Please, Can anyone help ?**
