This is the readme for the model associated with

J. J. Fox, J. L. McHarg, and R. F. Gilmour Jr,
Ionic mechanism of electrical alternans,
Am J Physiol Heart Circ Physiol 2002; 282: 516-530

and

Zheng I. Zhu and Colleen E. Clancy
Am J Physiol Heart Circ Physiol. published 12 October 2007,
10.1152/ajpheart.00476.2007

Usage:

The code author, Zheng Zhu, recreated the Fox et al. model in a C++
program which conforms to ansi so it can be built with gnu C++.  For
example under linux , compile with
 
g++ cellular_model_TS_mutation.cpp -lm -O4 -o ts

and then run with

./ts

(enter a file name like a.dat when asked)

The program iterates 100 times and finishes within a minute or so.
You can produce graphs after starting octave, for example, with
commands like

load a.dat
plot (a(:,1),a(:,3))

(graphs the voltage trajectory:)
