Coaxial couplers with high input RF power, usually operated at 500 MHz, are one of the critical components used in accelerators. To withstand high RF power, the couplers should be tested first, under identical conditions in a test stand. A waveguide coupled to a coaxial cable is used for this purpose. The parameter that indicates the amount of returned power loss is S11. By optimizing the dimensions of the proposed model this parameter can be reduced.​​ ​MATLAB program has special  and powerful tools to optimize the models which are simulated in CST STUDIO SUITE. In this paper the details of how MATLAB can control CST is described. Using MATLAB to control CST, the optimization of the coaxial coupler coupling 1800 waveguide is carried out.
