I have 2 vectors
a=[5 1 9 7 0 -5 1 -2]
b=[2 8 1 6 -8 -3 4 1] I need to create a vector c, which is made up of elements of b that are greater than a.
My attempt:
c=b(b>a)
c= 8 4 1
I don't know if I understand the question or it is that easy. Please help me!

It could be that easy, depending on how the question was phrased and what it wants you to do. From the documentation on Relational Operators < > <= >= == ~=
  • ‘The relational operators are <, >, <=, >=, ==, and ~=. Relational operators perform element-by-element comparisons between two arrays.’
(I got c = [8 -3 4 1] so I assume you left out -3.)

Yes, I left out -3. I was just making two random vectors and wrote the script without trying running it on matlab :) Thank you very much.
