MATLAB: How to change the values of edit boxes in a mask

maskparametersetsimulink

Hallo,
I was wondering how to change the values in the edit boxes of simulink block mask. If I understood the following Answer right, this is not possible: https://de.mathworks.com/matlabcentral/answers/98264-why-am-i-unable-to-change-the-default-value-of-a-block-parameter-using-the-set_param-function-in-sim
I would be really happy, if anyone can show me a way to get this done.
Greetings

Best Answer

Just use
get_param(gcb,'BC')
set_param(gcb,'BC','1');
