The REplot function creates a two-dimensional plot of a list of values from a recurrence, over the range rang where the range must be made up of increasing non-negative integers.

Remaining arguments are interpreted as plot options. See plot/options for a list of possible options.

The command with(LREtools,REplot) allows the use of the abbreviated form of this command.

$\mathrm{with}\left(\mathrm{LREtools}\right)\:$

$\mathrm{REplot}\left(\left(n^2+3n+2\right)g\left(n\right)+\left(-6-7n-2n^2\right)g\left(n+1\right)+\left(4n+5+n^2\right)g\left(n+2\right)\,g\left(n\right)\,\left\{g\left(0\right)=1\,g\left(1\right)=\frac{1}{2}\right\}\,0..50\right)$

$\mathrm{REplot}\left(\left(1-n^2\right)u\left(n+1\right)+\frac{3}{2}u\left(n-1\right)+\left(\frac{1}{2}+\frac{3}{2}n+n^2\right)u\left(n\right)\,u\left(n\right)\,\left\{u\left(0\right)=1\,u\left(2\right)=\frac{1}{2}\right\}\,i=0..50\right)$
