normrnd
              Random arrays from the normal distribution.
 r = normrnd (mu, sigma) returns an array of random
 numbers chosen from the normal distribution with mean mu and standard
 deviation 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 finite real numbers and
 sigma > 0, otherwise NaN is returned.
 When called with a single size argument, normrnd 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.
