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
