I have a wblfit error

I have an error with my wblfit. I am applying it to some data and I get the error: "X must be a vector containing positive values." I know that the data is a vector (I checked with isvector) and that all the values are greater than zero (I searched for values less than or equal to zero and got none). Now I really don't understand this error.

Nor do I understand it. But if I look inside wblfit I see it displays an error message if either of these is true:
if ~isvector(x)
% or
elseif any(x <= 0)
Can you double-check those conditions on your data?

Hi Tom,
Thanks. I noticed this too and did a quick check, but didn't get any zero values. However when I checked again there were indeed zeros in the data so problem solved.
