Provide an example which illustrates how to use the RKC package. Details about the RKC package: please take a look at the paper "RKC: An explicit solver for parabolic PDEs", B.P.Sommeijera, L.F.Shampineb & J.G.Verwera, Journal of Computational and Applied Mathematics, Volume 88, Issue 2, 2 March 1998, Pages 315-326.

Code is also available in Netlib, the file rkc_example1.f is modified to post processing in gnuplot.
