Function Reference: ncfinv

statistics: x = ncfinv (p, df1, df2, delta)

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

x = ncfinv (p, df1, df2, delta) the inverse of the noncentral F distribution with df1 numerator degrees of freedom, df2 denumerator 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.

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