Hello all,I have a very large set of numbers. I got the log and then used the following line to get the monthly mean Fine_avg = varfun(@mean,avgFine_table,'GroupingVariables','month');
for some reason i am getting -Inf and I'm not sure why. I tried removing all negative values and zeros before getting their Log, but no effect. This isn't happening to other sets of data. Can someone let me know what i'm missing or what i should check for.
thanks

One option is to use min(x) or min(abs(x)) with two outputs, so you can find at least one of the elements causing the problem.
