how can I save the output data of each run in new row ? I used append but it just overwrites the old values

Hi,
You can initialize an empty matrix with the desired number of rows and columns, and then use indexing to add each set of output data as a new row.
Here's an example:
% Initialize empty matrix to store output data
output_data = [];
% Loop through each run
for i = 1:num_runs
% Run some code to generate output
output = my_function(input_data);
% Append output data to matrix as a new row
output_data = [output_data; output];
end
% Save output data to a file
save('output_data.mat', 'output_data');

To save the output data of each run in a new row when append overwrites the old values
This can be done depending on the input data available.
  1. The number of runs are known:
MATLAB’s dynamic array functionality to create an empty matrix and append output from each run as a new row using an iterator thus it avoids the overwriting problem.
  1. The number of runs are unknown:
Then we can use a while loop instead of a for loop to keep iterating until a condition is met and may use a break statement to come out of the loop.
Hope this helps!
