Dear all,
I would like Octave code to implement the following equation system and to
plot (v) vs. time. However, I am at a complete loss how to do this. Could
anyone help? I would be so, so grateful. I am under quite a bit of time
pressure and haven't the time to get my Octave programming up to the heights
required to do this task in time. Please don't hesitate to write back if you
require any more info. I am using Octave as a module of cygwin on a
Windows XP machine. I have the GNUPlot module installed as well as Cygwin.
Once again. Thank you so, so much. All the best,
Michael

// Master equation
v' = -(ina+ik+ih+il)
// ina
ina = 0.000060*minf*(v-55)
minf = (1+exp(-(v--53.8)/3))^-1
// ik
ik = 0.000105*b*(v--85)
b' = ((binf - b)/btau)
binf = (1+exp(-(v--54)/5))^-1
btau = (3000 * (1/(cosh((v--54)/(4*5)))))
// ih
ih = 0.000200*h*(v--30)
h' = ((hinf - h)/htau)
hinf = (1+exp((v--76.4)/20))^-1
htau = (1/((((-2.89 * v) + -445)/(1-exp(((v+-445)/-2.89)/24.02))) + (((27.1
* v) + -1024)/(1-exp(((v+-1024)/27.1)/-17.4)))))
// Ileak
il = 0.000100*(v--70)
