Matlab matrix Row Manipulation?

Question

If I have a matrix:

A = [ 1 2 3 4 5 6]

how do I create another matrix from that so that it is:

B = [ 3 4 5 6]

Basically, I just want to take the first row off of a matrix and assign the remaining to a new matrix. I tried:

B = A ([2,:],:)

but that didn't work... Any help would be greatly appreciated, thanks!

Just a sidenote, if you want to select arbitrary rows, then do as follows: B=A([1 3 5 8 10],:). This will select only 1st, 3rd, 5th, 8th and 10th row. — Autonomous

You're close!

You can do like so:

B = A(2:end,:)

where you can use end to indicate the last column index of the array.
