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.
|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.
