Hey all,
I'm trying to use the wblfit function (within the statistics toolbox) and I'm having trouble actually running it. I do have the stats toolbox and when I do a help on the function, I get a description. When trying to run it, Matlab can't seem to find it. I feel like I'm missing something obvious here. Any ideas? See attached.

Your problem is MATLAB is like me. I can never figure out how to spell weibull. Is it i before e? And why does wblfit not have two L's in it?? I mean, I can't even figure out how to pronounce wblfit. So MATLAB gets confused. ;-)
Seriously, I'd first check to see if you can use other tools from the stats toolbox. normfit, or lognfit, for example?
I did check to see that wblfit was introduced long before R2012. So if you have a valid toolbox for your release, then it should be able to use wblfit.
wblfit(rand(100,1))
ans =
0.55071 1.4476

The first approach for such problems is to run these calls from the Command Window or a script:
restoredefaultpath
rehash toolboxcache
If that doesn’t work, Contact Support (link).
