Noncentral t inverse cumulative distribution function
X = nctinv(P,NU,DELTA)
X = nctinv(P,NU,DELTA) returns
the inverse of the noncentral t cdf with
of freedom and noncentrality parameter
the corresponding probabilities in
DELTA can be vectors, matrices, or multidimensional
arrays that all have the same size, which is also the size of
A scalar input for
expanded to a constant array with the same dimensions as the other
x = nctinv([0.1 0.2],10,1) x = -0.2914 0.1618
