Re: Contour plots

[Paul Kienzle]

Shai,

Here's how I hacked your contour.m to work with gnuplot.  Providing
gca, cla and line for gnuplot would be a better solution, but this
was good enough to show that contourc works:

function ret = contour(varargin)

  c = contourc(varargin{:});

if 0
  ca = gca();
  if (isempty(ca))
    cla();
  elseif (strcmp(get(ca,"nextplot"),"replace")),
    cla();
  endif
endif

  ## decode contourc output format
  held = ishold;
  i1 = 1;
  while(i1<length(c))
    ii = i1+1:i1+c(2,i1);
    plot(c(1,ii),c(2,ii),';;'); hold on;

    i1 += c(2,i1)+1;
  endwhile
  if ~held, hold off; end

  if nargout > 0, ret = c; end

endfunction
