Vectors with Uniformly Spaced Elements

MATLAB allows you to create a vector with uniformly spaced elements.

To create a vector v with the first element f, last element l, and the difference between elements is any real number n, we write:

v = [f : n : l]

Example

Create a script file with the following code:

v = [1: 2: 20];
sqv = v.^2;
disp(v);disp(sqv);

When you run the file, it displays the following result:

1 3 5 7 9 11 13 15 17 19
1 9 25 49 81 121 169 225 289 361
