CST Studio Suite 

Dear all, 

I am trying to use the Matlab to define an excitation signal in the Circuit & Systems of the CST through the VBA. 

Referring to the example below: 

 2. example for other signal type with different string array size

    .Reset
    .Name "Tran2"
    ReDim arr(3) As String  ' (3) means (0 To 3)
    arr(0)="0"  ' Fmin
    arr(1)="1"  ' Fmax
    arr(2)="2"  ' Ampl
    arr(3)="false"  ' Use FMin/Fmax from Task (optional)
    .SetPortSignal("1", "Gaussian", arr)  ' Need 3 definitions (optional 4) To define a gaussian signal

I am writing the MATLAB code as below:

SimulationTask = invoke(mws,'SimulationTask');
values=["'0'","'1'","'2'"]; % values is a string array in the CST
invoke(SimulationTask,'SetPortSignal','1','Gaussian',values);  % 

however, there is always an error as below:

Error using Interface.CSTStudio_application.OpenFile.SimulationTask/invoke
Call failed, Dispatch Exception:
Source: CST DESIGN ENVIRONMENT 2024
Description: Invalid signal definition (not a valid string array).

How can I solve this problem?

Thanks!
