how to make an identifer for string variables

Hi I have a list of string variables, which all ends with "_STI". How can I group them together so that I can perform the same operations to them. For example, I want to assign a number to all the variables ends with "_STI". Thanks very much

Hello Linden,

Assuming that the variables are doubles, here is a small example to achieve value assignment by grouping the variables together:

% Step 1: Get a list of all variables in the workspace
vars = who;

% Step 2: Initialize a number to assign
assign_value = 42; % Replace with the number you want to assign

% Step 3: Loop through the variables and perform operations
for i = 1:length(vars)
    var_name = vars{i};
    if endsWith(var_name, '_STI')
        % Use dynamic field names to assign a value
        assignin('base', var_name, assign_value);
    end
end

You can modify the code according to your data type requirement.

I hope this helps!
