r = ncx2rnd (df, lambda) returns an array of random numbers chosen from the noncentral chi-squared distribution with df degrees of freedom and noncentrality parameter lambda. The size of r is the common size of df and lambda. A scalar input functions as a constant matrix of the same size as the other input.

When called with a single size argument, ncx2rnd returns a square matrix with the dimension specified. When called with more than one scalar argument, the first two arguments are taken as the number of rows and columns and any further arguments specify additional matrix dimensions. The size may also be specified with a row vector of dimensions, sz.
