filling an array
...he
following.
I want to declare array I with a specific length and then alternatively
fill it with 10 zeros and 10 specified values:
v<- 14
I <- c(0,length(t))
But in stead of just filling I with 0 I want 10 zeros and then 10 fourteens
(i.e. the value in v)
Hope that makes sense.
Regards
Jannetta

A Hodgkin Huxley Model
...lt;- a*(b*v-u);
if (v>=30) v<-c else v<-u+d;
list( c(dv, du))
})}
parms=c( a=0.02, b=0.2, c=-65, d=8,I=10);
times=seq(from=1, to=1000, by=1);
init=c(v=-65, u=0.2);
out<-ode(y=init, times=times, func=Izhikevich, parms=parms)
plot(out)
Can someone perhaps help me out?

Running Sage from a Samba server
...there could be any Samba
issues that might be causing this as obviously, Sage support is now
starting to blame the unknown to them in this equation, which is Linux
(and off course Samba).
Any suggestions would be appreciated.
Thanks

Error in J[time] : invalid subscript type 'closure'
...ere is a short bit of code
that produces the error:
s_fun <- function(parms,time) {
with(as.list(c(parms)),{
print(J[time])
})
}
times = seq(from=0, to=100, by = 0.1);
v<-14
J<-c(rep(c(rep(0,10),rep(v,10)),5))
parms=c(J)
out <- s_fun(parms, time)
Thanks for your help
Regards

using and event in deSolve
...ng the root to init[1]+30 did not
produce the desired result, making it init[1]-30, produced something better
but I'm not sure that it is right yet.
The actual equations are:
v' = 0.04v^2 + 5v + 140 - u + I
u- = a(bv-u)
If v=30mV
then v-, u-u+d
Any help would be appreciated.
Kind Regards
Jannetta

An extended Hodgkin-Huxley model that doesn't want to work.
...52, CaSm=0.52,
Napm=0.52, Naph=0.52, hm=0.52, Km=0.52,
KCam=0.52, Am=0.52, Ah=0.52, ECa=-80);
out<-ode(y=init, times=times, func=HH_soma, parms=parms);
o<-data.frame(out);
plot(o$time, o$v, type='l');
Please ask if any further information is required.
Many thanks
