Does odeFunction(expr, vars) have a maximum number of symbolic variables/equations?
I ask because I am working with a rather large (total = N^3) number of ODEs. When N=10 or less, my code runs. When N=11, I get
Error using mupadengine/feval (line 187)
Duplicate variables specified in second argument.
Error in sym/odeFunction (line 118)
A = feval(symengine, 'daetools::odeFunction', expr, vars, params{:});
Error in MAIN (line 212)
ode_fun = odeFunction(x_dot,x);
when calling odeFunction.

I found a different way to set up my ODEs so I don't need symbolic variables and therefore odeFunction (thus, avoiding the problem), but I am still curious about this.

I have brought this issue to the notice of our developers. They will investigate the matter further.
