Vector In Matlab

In Matlab, data structure vector and matrix:

>> id = [4 5 6 2 4]

4 5 6 2 4

>> id = 1:5    % start:end

1 2 3 4 5

>> id = 1:2:10    % start:step:end

1 3 5 7 9

How to access elements in matrix:

>> id = [4 5 6 7 8]

4 5 6 7 8

>> id(1)    % Get the 1st element of the id

4

>> id([1 2 3])    % Get the 1st, 2nd, 3rd elements of id

4 5 6

>> id(1:3)    % Get the 1st till the 3rd elements

4 5 6

>> id(end)    % Get the last element
8
