Hello,

I am trying to use distribution fit but i have the following:

Error in ==> distributionfit at 106
offset = -min(data)+0.001*range(data);

Please help.

05 Oct 2008 DistributionFit Fits normal, lognormal, and weibull distributions to data Author: J. David Cogdell Lin, Ying

??? Error using ==> extent at 9
EXTENT function is obsolete. Get the 'Extent' property of the text object instead.

Error in ==> DistributionFit2 at 181
ext = extent(trd);
