WebNov 30, 2024 · Theta is a measure of the rate of decline in the value of an option due to the passage of time. It can also be referred to as the time decay on the value of an option. If … Web[Euler's method and Runge-Kutta can also be generalised in this way]. (2) Whenever you have an implicit method for solving a DE you will have to use fixed point iteration or a Newton-Rhapson type method at each step to find y(:,j+1). [Again, this should be familiar to you if you've implemented any implicit Runge-Kutta methods] $\endgroup$
