Hello,
It's not necessary to define the additional copy/constructor
functions.
You only need to pass around a pointer to the data rather than the
data itself, in addition to the system parameters.
e.g. for 25 double parameters 'x' and an arbitrary set of data
struct mysystem {
double x[25];
struct mydata * data;
}
The size parameter should then be sizeof(struct mysystem).
