statistics: x = ncx2inv (p, df, delta)

Inverse of the non-central chi-square cumulative distribution function (iCDF).

x = ncx2inv (p, df, delta) returns the inverse of the noncentral chi-square distribution with df degrees of freedom and noncentrality parameter delta, at the probabilities of p.

The size of x is the common size of df and delta. A scalar input functions as a constant matrix of the same size as the other inputs.

ncx2inv uses Newton’s method to converge to the solution.
