Hi everyone,
I'm trying to do a fitting of a system of differential equations and I'm getting a odd results, I've been surfing a bit but did not found something.
SystemN = {
u h'[t] == - a x[t] h[t],
n'[t] == -s[t],
u x'[t] == c r[t] z[t] - a h[t] x[t],
u y'[t] == d y[t] - c r[t] z[t],
1 == x[t] + y[t] + z[t],
r'[t] == s[t] - c z[t] r[t],
1 == r[t] + s[t],
h[0] == H0/PxT,
n[0] == N0/TT,
x[0] == PxT/PxT,
y[0] == 0,
z[0] == 0,
r[0] == TT/TT,
s[0] == 0
}
this is my system of equations, and then I try to get a parametric solution for n with respect to c and d (all the rest u,a,N0,H0,PxT,TT are …
