Reaction-Diffution Equations: Turing Instability
Turing_Pattern.pdfI discuss some of the important aspect of GNUPLOT. In the following I give a script to plot four subplots in a multiplot. The datafile files may be obtained from the LINK (sniper_chimera.txt) provided.
save the following script as "filename.plt"
