Hello everybody,

I am trying to build the following equation with Origin C but unforunately I don't have a clue how to do it. I would be very happy if somebody could help me.

The equation goes (Logan et. al 1976):

y=a*(exp(B*x)-exp*(B*Tm-t))
when
t=(Tm-T)/#916;T

I don't know is it even possible to use #916; in the equations, or can I use "when" command?

Thank you,
Martta

If this is a fitting function and your parameter values are:
Tm, T, a and B then you can use:

t = (Tm - T) / 916.0;
y = a * ( exp(B * x) - exp(B * Tm - t) );

Neither C nor Origin C use # for variable typing.
