I want find mean of out.txt file such that this file is replaces at every iteration and hence values changed.

Hello everyone.

How are you?

I have a question here. With every iteration I have an output.txt file generated such that values vary with each iteration. Now I want to find the mean of each iteration till 100 iterations and store the mean in some variable ( say m1 to m100) or if there is any other representation in a txt or excel file also. Please help me how to code it such that my mean is calculated based on the present file generated.

I have attached here two output files (out) for two iterations but this can go to 100. You can try with 5 such different output files.

Thank you,

Adeline

Let's say you have 100 iterations, and data is a vector containing the numbers written to file on each iteration. Then to calculate the mean of data on each iteration and store those means, you could say:

n_iterations = 100;

% initialize a vector to store the means:
data_means = zeros(1,n_iterations);

for ii = 1:n_iterations
    
    % ...
    % whatever code calculates 'data'
    % ...
    
    % store the mean of the current 'data' in element ii of 'data_means':
    data_means(ii) = mean(data);
    
end

Or, if you don't know how many iterations there will be:

% initialize a vector to store the means:
data_means = [];

while true % some condition that will eventually be false
    
    % ...
    % whatever code calculates 'data'
    % ...
    
    % store the mean of the current 'data' in a new element of 'data_means':
    data_means(end+1) = mean(data);
    
end
