Announcement text:
matlab.mp ------- Metapost data plotting in matlab style

Matlab has powerful data plotting ability, but one annoying problem
prevents it from being perfect: when you increase the linewidth, the
dotted line size stays the same, so the plotted line no longer looks
like a dotted line.

another problem is matlab bug: it oftern cuts away some curves and

plus, matlab is expensive. on the other hand, the free gnuplot also
doesn't produce very satisfactory visual effects.

I got accustomed to matlab's easy interface. so I want to integerate
the powerful graphic function of Metapost and the easy interface of
Matlab. so I wrote this script matlab.mp. this is based on graph.mp, I
just collected the data into 2-D arrays, and remembered the line
styles, so it's easy to plot out legends.

all kinds of line color, width, style (dotted/dashed, etc), and
markers. you can easily expand this by modifying the code.

easy interface. very similar to matlab

full power of latex in caption/legends, by using the latexmp package.

Thanks for the upload
