Hi, I've run in to some problems using matlab and was wondering if anyone here could help me out.
I'm not quite certain if this is possible. But I have 2 functions and I would like to take the partial derivative of three variables, without knowing a single value. Is this possible? If so, how?
ex)
P1 = (K*P0*exp(r*t))/(K+P0*exp(r*t))
is one of my functions and I would like to take the partial derivative with respect to K, PO, and r.
Thanks in advance! Chris
