MATLAB CVX工具箱遇到矩阵相乘该怎么处理

MATLAB CVX工具箱遇到矩阵相乘报错

cvx_begin sdp quiet
cvx_solver sdpt3
variable T(Lv,Lv) hermitian toeplitz
variable W(Lv,Lv) complex semidefinite
minimize(2trace(WT)）;

Disciplined convex programming error:

Only scalar quadratic forms can be specified in CVX 

W*T这块报错，不知道遇到这种情况该怎么处理
