Hey, i have a small problem with a program i am writing in an mandatory task.
I am suppose to find the maximum value of one elemt minus the other elemt in a row vector, and do this for each element.
so far i have done this:
a = [2 8 9 5 4 9 7 6];
for j = 2:8
c = max(a(j-1) , a(j));
disp = c
end
What i further wish, is to make a new vector consisting of each of these maximums elements. How would i do that?

You can do this without using a FOR loop - keep it vectorized. I think that the following code achieves the results you're seeking:
c = max(a(1:end-1),a(2:end))

The fast fix of your code (without removing the for loop)
c(j) = max(a(j-1) , a(j));
Inside the loop c will always be assigned the result of the last iteration of the loop. If you want to have a vector of the results you have to use indexing for the result vector as well.
