% xy - matrix of soft (real-valued) outputs [n,m]
% theta - matrix of thresholds (one vector per row) [n,l-1]

function [y] = m3fSoftmax(xy,theta)
  [n,m] = size(xy);
  [n1,l1] = size(theta);
  if n ~= n1
    error('sizes of xy and theta don''t match');

  for i=1:l1
    tmp = theta(:,i)*ones(1,m);
    tmp = xy >= tmp;
    y = y + tmp;
    clear tmp;
