How to write these formulas in Matlab?

[r.valice]

Hi, all. I'm new with Matlab. Anyone knows how to write these formulas in Matlab?

Homework Statement

I need to write the following formulas in Matlab. The definitions are as follows.

1. $$p_{f}$$: the wireless link layer frame error rate
2. $$\tau$$: the wireless link layer inter-frame interval
3. $$p_{i,j}$$: the probability that the first frame transmitted by the node is received correctly by the router, being the $$i$$th retransmitted frame at the $$j$$th transmission trial.
4. $$t_{f}$$: the one-way frame transportation delay between the node and router.

5. n = 3
6. $$p_{f}$$ = 0 ~ 0.5
7. $$\tau$$ = 20ms

Homework Equations

Please, see the attached picture where the formulas appear.

The Attempt at a Solution

I'm trying to write it many times. I spent with it for a couple of days, but I cannot.

What I want to have is the MATLAB code that displays $$t_{f}$$ values as $$p_{f}$$ is increased from 0 to 0.5.

Thanks in advance!

Do you know how to implement a summation using a for loop? It's probably helpful for you to show us what you have done.

Umm...actually, I don't have any ideas for solving it. I'm expecting people who knows a bit about Matlab can do it easily. But, I cannot do it because I just started to use Matlab this month.

Thanks.

Sure there are people here who could do it easily, but I doubt that anyone will without you putting some effort into it first. We're not here to do your work for you, but are more than willing to help steer you in the right direction.
