if i replace num with real num, like 17, it works, any one who knows why?

Please take a look here.

I'm not familiar with this function, but as you declared num before, try to call it without ' '.

set_param('text/BC1', 'Inputs', num);

Cheers

thanks for your suggestion, i try it but still not working, but when i update the command as following, it works well. (i do it with matlab 2020b)

set_param('text/BC1', 'Inputs', num2str(num));

NOTE:set_param('text/BC1', 'Inputs', num) can works in matlbR2018b
