Very basic (and provisional) drawing tools using gnuplot and imageMagick.
This module is deprecated. It will be replaced by improved drawing tools based
on the Gnuplot package by Henning Thielemann.


Synopsis 



Documentation 


plots several vectors against the first one



Draws a list of functions over a desired range and with a desired number of points
> plot [sin, cos, sin.(3*)] (0,2*pi) 1000



Draws a parametric curve. For instance, to draw a spiral we can do something like:
> parametricPlot (\t>(t * sin t, t * cos t)) (0,10*pi) 1000



Draws the surface represented by the function f in the desired ranges and number of points, internally using mesh.
> let f x y = cos (x + y)
> splot f (0,pi) (0,2*pi) 50



Draws a 3D surface representation of a real matrix.
> mesh (hilb 20)
In certain versions you can interactively rotate the graphic using the mouse.





From vectors x and y, it generates a pair of matrices to be used as x and y arguments for matrix functions.



writes a matrix to pgm image file



imshow shows a representation of a matrix as a gray level image using ImageMagick's display.
