What is the solution?

Plot columns 2 and 3 of the following matrix A versus column 1. The data in column 1 are time (seconds). The data in columns 2 and 3 are force (newtons). A = £ 0 -7 6 5 -4 3 10 -1 9 15 1 0 20 2 -1

If you show us what you've done to try to solve this problem (which sounds like a homework assignment) we may be able to offer some suggestions to help you.

P.S. Please use a more descriptive title for your questions in the future.

Hi, I agree with Steven that you should probably show us your attempt at the problem and tell us where exactly are you encountering a problem.

To get you started, try something like:

A = [1 2 3; 4 5 6; 7 8 9];
plot(A(:,1),A(:,2));

Here, before you type in this code, just check what A(:,1) gives. This should give you an idea of how MATLAB handles indices. Once you figure this out, the rest should be obvious. All the best.

Cheers.
