Warning: SDP constraint evaluated to trivial true.

Hi,

I have this error when i am running my programme.

Warning: SDP constraint evaluated to trivial true. 

> In constraint.constraint at 43

  In sdpvar.le at 15

Warning: Solver not applicable (cplex)

kindly, let me know what could be possibility wrong.

Regards

triviall true means you have code similiar to ...F = [F, 0*x >= 0] or x>=x etc. The expression evaluates to a constant which satisfies the constraint

Solver not applicable means you think you have a QP (or LP or SOCP etc) but it is not. The model is too complicated for cplex. Most likely you have a semidefinite constraint, or a bilinear constraint (display your constraints!)
