@sam jones: it is great that you have some homework, but you forgot to actually ask us a question. What is your question for us?

To start plese use function sub2ind

[Andrei Bobrov]

Please read about sub2ind

[Andrei Bobrov]

hm.

Please see on this:

ii = [3 4 3 2 1 2];
jj = [1 2 3 4 5 6];
elev = E(sub2ind([m,n],ii,jj))

@sam jones: Programming should not be a question of luck. Try it and if it does not work as expected, post the following details:

1. The current code
2. Explanation of what the code does (perhaps a complete error message)
3. Explanation of what you expect it to do instead

Ask specific questions to get help in this forum. The statement "no luck :(" does not allow for an assistance, such that it only wastes your time. See https://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer

function [ELEVATION] =  FindPathElevationsAndCost (ii,jj,E)
[m,n] = size(E);
ELEVATION = E(sub2ind([m,n],ii,jj));
