Random matrices from the noncentral chi-square distribution.
Syntax
R = ncx2rnd(V,DELTA) R = ncx2rnd(V,DELTA,m) R = ncx2rnd(V,DELTA,m,n)
Description
R = ncx2rnd(V,DELTA) returns a matrix of random numbers chosen from the non-central chi-square distribution with parameters V and DELTA. Vector or matrix inputs for V and DELTA must have the same size, which is also the size of R. A scalar input for V or DELTA is expanded to a constant matrix with the same dimensions as the other input.
R = ncx2rnd(V,DELTA,m) returns a matrix of random numbers with parameters V and DELTA, where m is a 1-by-2 vector that contains the row and column dimensions of R.
R = ncx2rnd(V,DELTA,m,n) generates random numbers with parameters V and DELTA, where scalars m and n are the row and column dimensions of R.
