store different output in single file for every combination of varible

I have two variables named parameter_x=[5 5]. output is s11. whenever I change this parameter_x value different s11 is coming. but I want to preserve all s11 value for every combination .how to store in single file.

param_X = [5 5];
runPyCmd = ['ipy64 OPTScript.py ', num2str(param_X)];
[~,msg] = system(runPyCmd);
SData_original = readtable('S11.csv', 'VariableNamingRule', 'preserve')
figure(1)
plot(SData_original{:,1},SData_original{:,2},'r--');
xlabel('Freq (GHz)'); ylabel('S11 (dB)'); grid on; hold on;

There is no parameter_x (though there is param_X) or s11 in the code you've posted. In any case, it sounds like a simple loop will do what you want,

I'm assuming SData_original returned by the readtable function is a 1-by-2 table and the values in each column of the table is a scalar. If my assumption is correct, this code will address your need:

% This routine will prompt you to input the param_X value repeatedly, one at a time.
% When you have entered all your values, type END to exit the routine and plot the results.

SData = []; % Initialize an array to store all output values
while true
    % Prompt to enter param_X or the string 'END'
    param_X = input('Enter an array (e.g., [1 2]) or a string (e.g., END): ', 's');
    % Check if the user wants to end the loop
    if strcmpi(strtrim(param_X), 'END')
        break % Exit the loop if 'END' is entered (case-insensitive)
    else
        runPyCmd = ['ipy64 OPTScript.py ', param_X];
        [~,msg] = system(runPyCmd);
        SData_original = readtable('S11.csv', 'VariableNamingRule', 'preserve');
        
        % Store the first and second columns of the table in the array
        SData(end+1,1) = SData_original{:,1};
        SData(end,2) = SData_original{:,2};
    end
end
figure(1)
plot(SData(:,1),SData(:,2),'r--');
