function cdfplotmed(x,plottype)
% DESCRIPTION cdfplotmed(x)
%  CDF plot of the input matrix for each
%  column separately. By use of a linear scale
%  the middle part of the input is highlighted.
% INPUT
%  x --  a real matrix (no Nans or Infs)
%  plottype --  String describing the plot, e.g. 'r*'
%               plots red stars.
% OUTPUT
%  only the plot
% TRY
%  cdfplotmed(randn(10000,1))
