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
