r = hnrnd (mu, sigma) returns an array of random numbers chosen from the half-normal distribution with location parameter mu and scale parameter sigma. The size of r is the common size of mu and sigma. A scalar input functions as a constant matrix of the same size as the other inputs.

When called with a single size argument, hnrnd 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.
