logirnd
              Random arrays from the logistic distribution.
 r = logirnd (mu, sigma) returns an array of
 random numbers chosen from the logistic 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.
 Both parameters must be reals and sigma > 0.
 For sigma <= 0, NaN is returned.
 When called with a single size argument, logirnd 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.
