## @deftypefn {Function File} {} wiener_rnd (@var{t}, @var{d}, @var{n})
## Return a simulated realization of the @var{d}-dimensional Wiener Process
## on the interval [0, @var{t}].  If @var{d} is omitted, @var{d} = 1 is
## used. The first column of the return matrix contains time, the
## remaining columns contain the Wiener process.
##
## The optional parameter @var{n} gives the number of summands used for
## simulating the process over an interval of length 1.  If @var{n} is
## omitted, @var{n} = 1000 is used.
