I have an excel file with a table 1442x31. I have extracted the 3 columns I want to calculate on a different table, named cols. Cols table size is 1439x3
And I want to calculate the mean and standard deviation of each of these columns.
I tried these:
mean_val = mean(cols);
stan_dev = std(cols);
But the result on both of mean and std was [NaN NaN NaN].

Implies the values have some NaN entries.
Try once
mean_val = mean(cols,'omitnan');
stan_dev = std(cols,'omitnan');
Hope this helps
