I have been sent some complete MATLAB script. It appears that author of this code has made a specific instruction using num2str and set_param .
What is the purpose of the following line:
['[' num2str(operating_point) ']']
I am interested specially of an intention of using '[' as syntax.
set_param(system_block_name, operating_point_name,...
['[' num2str(operating_point) ']']

Yes, yes. I do understand what doesnum2str. I was wondering why the author of that code used braces in apostrophe'['and']', because I think it's unnecessary.

Then you didn't actually try the command, or you would see what the single-quotes do. I wasn't trying to get you to runnum2str, I was trying to get you to execute the part you had the actual question about.

In MATLAB rectangular braces [] create vector/matrix.
By default, horizontal vector of strings concatenated into 1 string:
['str1','str2'] % produces str1str2
So
['[',']'] % will print []
num2str() converts number into string:
a=10;
my_str = ['[',num2str(a),']'] % will assign my_str = '[10]'
set_param() is some function that gets 3 parameters, where 3rd one is your string
