how can i store the result which i am obtaining on command window and store it on in excel file, i have tried but still not able to solve it out.

% Initialize variables
numIterations = 10;
outputResults = zeros(10, numIterations);

% Perform iterations
for iteration = 1:numIterations
    
    % Generate random results for each iteration
    result = rand(10, 1);
    
    run('start.m');           % my main program to be run for 10 iterations%
    % Store results in outputResults matrix
    outputResults(:, iteration) = result;
end

% Create a table from the outputResults matrix
resultsTable = array2table(outputResults);

% Export to Excel
writetable(resultsTable,'resultsTable.xls')

What is the relation of the script start.m with the data being saved (i.e. result)?

[Walter Roberson]

I suspect that start.m is displaying something to the command window, and that the user is hoping to capture what was displayed.

[Ashish Das]

yes, walter robertson.

Why not define the code as a function and provide the data you want to save in terms of output variable(s)?

This way you can call the function in each iteration and store the data accordingly.

What is it, that is displayed on the command window which you want to capture?

If you cannot modify the script for some reason, then change

    run('start.m');           % my main program to be run for 10 iterations%

to

    start_results = evalc('start');

and then use tools such as regexp() to extract the parts you want out of the output.

But if you can modify the script to return a value, that would almost always be better.
