 Portability uses gnuplot and ImageMagick Stability provisional Maintainer Alberto Ruiz (aruiz at um dot es)
Description

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.

Documentation
 mplot :: [Vector Double] -> IO () Source
plots several vectors against the first one
 plot :: [Vector Double -> Vector Double] -> (Double, Double) -> Int -> IO () Source

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
```
 parametricPlot :: (Vector Double -> (Vector Double, Vector Double)) -> (Double, Double) -> Int -> IO () Source

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
```
 splot :: (Matrix Double -> Matrix Double -> Matrix Double) -> (Double, Double) -> (Double, Double) -> Int -> IO () Source

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
```
 mesh :: Matrix Double -> IO () Source

Draws a 3D surface representation of a real matrix.

``` > mesh (hilb 20)
```

In certain versions you can interactively rotate the graphic using the mouse.

 mesh' :: Matrix Double -> IO () Source
 meshdom :: Vector Double -> Vector Double -> (Matrix Double, Matrix Double) Source
From vectors x and y, it generates a pair of matrices to be used as x and y arguments for matrix functions.
 matrixToPGM :: Matrix Double -> String Source
writes a matrix to pgm image file
 imshow :: Matrix Double -> IO () Source
imshow shows a representation of a matrix as a gray level image using ImageMagick's display.
 gnuplotX :: String -> IO () Source
 gnuplotpdf :: String -> String -> [([[Double]], String)] -> IO () Source
