Hi! I'm trying to apply weibull parameter estimate to every coloumn except for the first one i have on a table. Am I using the syntax correctly?

TtrnPosArray = table2array(TtrnPos);
C = num2cell(TtrnPosArray,1)
fitTableWbl = cellfun(@wblfit, C(:,2:171))

Thanks.

The input to wblfit should be a vector containing only positive values, as the error suggests.

Make sure your TtrnPosArray contains only positive values. You could remove/replace the columns which consist of non-positive numbers.
