Hello, I have a table where GroupingVariables is month. It has 3 columns, the month, the groupcount, and the mean. I would like to get the exponential of just the third column of the table. How can that be done without having to extract the column and use horzcat? i used varfun to get the mean, so the columns have names. Thanks.

I tried using the command below
Fine_avg = varfun(@exp,Fine_avg,'InputVariables','mean_Fine_pearllog');
it gives the correct values, but then removes the first two column. :/

Do individual table entries have multiple values? If not then
Fine_avg.mean_file_perl = exp(Fine_avg.mean_File_pearllog);

You can assign back your calculation to the original table like this:
Fine_avg(1:end, 'mean_Fine_pearllog') = varfun(@exp,Fine_avg,'InputVariables','mean_Fine_pearllog');
