What is the return mean by weibfit

I 'd like to use weibfit to estimate the weibull parameter of a set of data. the data is [50289, 58591, 54746, 65539, 58292, 55714], but the return is [0.000 12.656], what is that mean? the weibull slope could be 12.656, but what is 0.000 mean?

What version are you using?

doc weibfit

in R2011b tells me to use wblfit

doc wblfit

explains the outputs.

Sean is right, and in fact the reason why you should use wblfit, not weibfit, if you can is exactly what you saw: the parameterization used in weibfit often leads to the first parameter being very small - 4e-61 in this case. Change your display format to short g and you'll see something other than zeros.

Hope this helps.
