the condition is (if the first value in the column is less than or equal to a certain number then extract the whole column)

10 by 13 vector, in a for loop

在 MATLAB Online 中打开

mask = TheArray(:,1) <= ACertainNumber;
output = TheArray(mask, :);

@Walter Roberson I highly appreciate your approch. I have a similar problem only the difference is in my case ACertainNumber is in a range e.g., 1-2 and then 2-3 and so on. Additionally, I need to compute the mean of ACertainNumber of all the selected coloumns. May you suggest any possible wayout.
