chi2inv

Chi-square inverse cumulative distribution function
collapse all in page
Syntax

X = chi2inv(P,V)
Description

X = chi2inv(P,V) computes the inverse of the chi-square cdf with degrees of
freedom specified by V for the corresponding probabilities in P. P and V can
be vectors, matrices, or multidimensional arrays that have the same size. A
scalar input is expanded to a constant array with the same dimensions as the
other inputs. The degrees of freedom parameters in V must be positive, and
the values in P must lie in the interval [0 1].

This is the same for chi2cdf | chi2pdf | chi2rnd | chi2stat | icdf....

Do you have a little idea where I can find these chi functions?

Regards,

Michel
