MATLAB allows you to create vectors with uniformly spaced elements.
To create a vector v with the first element f, the last element l, and the difference between elements as any real number n, it is written as:
v = [f : n : l]
Create a script file using the following code-
v = [1: 2: 20]; sqv = v.^2; disp(v); disp(sqv);
When running 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
