To open up Octave, open up your terminal and type 'octave'. This prompts you with a screen of credits, followed by 'octave:1>'
Let's compose a three dimensional matrix equation, which we will call 'A'
A would be written as so like so:
In terminal, we can write this as A = [3, 2, 4; 2, 0, 2; 4, 2, 3]
If we type 'A' in terminal, the matrix we inputted should be displayed see image be below:
Now we have matrix 'A' in the memory of our terminal session
We will now establish matrix 'b', which is a 3x1 matrix.
Establish matrix 'b' using the same syntax we did with 'A', and recall the matrxi
We will now compute unknown variables x1, x2, and x3. A written representation is in the picture below
We can compute the unknown variables by recalling the two matrices we've composed
We have solved all Unknown variables. We have:
