Matrix of ones in Octave

In this lesson I'll explain how to make an all-ones matrix in Octave.

I'll give you a practical example.

Create a 3x3 square matrix of ones. Type ones(3,3)

>> ones(3,3)
ans =
1 1 1
1 1 1
1 1 1

Now, create a 3x4 matrix of ones. Type ones(3,4)

>> ones(3,4)
ans =
1 1 1 1
1 1 1 1
1 1 1 1

The first parameter of the ones() function is the number of rows while the second parameter is the number of columns.

This way you can create matrices of any size.
