r = stdrrnd (k, df) returns an array of random numbers chosen from the studentized range distribution for k groups and df degrees of freedom: the range of k standard normal variables divided by an independent sqrt (chi2 / df). The size of r is the common size of k and df. A scalar input functions as a constant matrix of the same size as the other input. k must be an integer of at least 2 and df positive, Inf included; otherwise NaN is returned.

When called with a single size argument, stdrrnd 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.

MATLAB has no public counterpart of this function.
