Equality constraints represented as LMIs

212 Views Asked by At

I have three complex variables

$$x=\begin{bmatrix} x_1 & x_2 & x_3 \end{bmatrix}'$$

two complex knowns

$$d=\begin{bmatrix} d_1 & d_2 \end{bmatrix}'$$

and two equality constraints

$$x_1x_2 = d_1$$

$$x_1x_3 = d_2$$

I would like to know how to represent the equality constraints in linear matrix inequality (LMI) form so that I can use an SDP solver.

P.S. This is my first time posting a question, so tips on refining the question itself are also appreciated.
