# ncx2rnd

Noncentral chi-square random numbers

## Syntax

R = ncx2rnd(V,DELTA)
R = ncx2rnd(V,DELTA,m,n,...)
R = ncx2rnd(V,DELTA,[m,n,...])

## Description

R = ncx2rnd(V,DELTA) returns a matrix of random numbers chosen from the noncentral chi-square distribution using the corresponding degrees of freedom in V and positive noncentrality parameters in DELTA. V and DELTA can be vectors, matrices, or multidimensional arrays that have the same size, which is also the size of R. A scalar input for V or DELTA is expanded to a constant array with the same dimensions as the other input.

R = ncx2rnd(V,DELTA,m,n,...) or R = ncx2rnd(V,DELTA,[m,n,...]) generates an m-by-n-by-... array. The V, DELTA parameters can each be scalars or arrays of the same size as R.
