Shapiro Wilk test in objective-c

问题

I would like to perform a test for normal distribution using the well known Shapiro-Wilk test. I can find many resources with more or less good informations about the test. But I couldn't find any information about implementation the test in c-code. Is there something out there in c or objc dealing with Shapiro-Wilk?

Thanks!
