nctinv (Statistics Toolbox)

Inverse of the noncentral T cumulative distribution.

Syntax

X = nctinv(P,NU,DELTA)

Description

X = nctinv(P,NU,DELTA) returns the inverse of the noncentral T cdf with NU degrees of freedom and noncentrality parameter, DELTA, for the probabilities, P.

The size of X is the common size of the input arguments. A scalar input functions as a constant matrix of the same size as the other inputs.

Example

x = nctinv([.1 .2],10,1)

x =

   -0.2914    0.1618
