a = -5:1:-2
b = [-12, 0, -3, -6]
c = 0:-2:-7
What answer will the following commands produce in Matlab?
(a < b) & (a < c)
(b > c) | (a < c)
(b ~= c) | 1
~(b > c) & ( a > b)
(~c | a) & b

The steps are:
- Log in to MATLAB
- Enter those commands exactly as written
- See what the output looks like
- Submit that answer to your teacher
[Feel free to ask some specific questions if you get stuck at any of those steps.]

CTRL+C, CTRL+V in the command window. Then I'd write down the results. If you were really fancy you could use the diary function so you don't even have to write down the results. On a test, I would read the logical conditions just like MATLAB and respond accordingly. Computers are dumb, they don't think on their own, and they do EXACTLY what you tell them. This makes it very easy for us to predict what their results will be.

If it was a written test, then I would apply my knowledge of the effects of each of the operators and of what is calculated by "if". That knowledge has been obtained by reading the documentation about each operator.

Personally I would have read the stuff you are supposed to have read and just "know what the symbols mean". Sorry
