Integrates the ODEs from time 0 to
tf.
Reports the function values at tR.
The embedded ODE's are in Fig., with
(x, y, y)0 the given
initial values.
This applies, from Python: for integration,
'scipy.integrate' 'odeint'; and, for optimization, 'minimize'.
Advantage is taken from: PHP,
for the web page; Python for the numerical segment;
and 'gnuplot', for plotting.
Draws a plot of the data. |

Computation structure — A PHP file
(this page: 'P.reverse.php') calls (via
'action=...') an intermediate PHP file ('Reverse.php'), which
(through $_POST) sends the problem data as command line arguments to
a Python script. This last does the computing, and makes
'system' call(s) to 'gnuplot', for the final (temporary) webpage.
Files involved:
P.reverse.php (this one),
Reverse.php,
reverse.py.
Keywords: reverse kinetics; PHP;
Python; gnuplot. |
