In this section, we would see how we can use GNU Octave using a simple example. We are basically adding two matrices.

So, lets say we have A and B matrices.

Values for A – [1,2 ; 3,4]
Values for B – [5,6 ; 7,8]

Launch GNU Octave –

And, in the interface issue the following –

>> A=[1,2;3,4]

and Enter. It would display the output –

A =

    1   2
    3   4


>> B=[5,6;7,8]

It would display the output –

B =

    5    6
    7    8

And, do

>> A+B

We get the following output –

ans =

    6    8
    10   12
