I followed the Instructions "Read this first!!" For acquiring a copy of Octave.  I just copied it to my flash drive from a computer lab pc.
You can abort any command in octave by pressing Ctrl C.


I played around with Octave as instructed, But I still don't understand it very well.  I plotted a couple graphs, but I don't understand the proper syntax format for Octave,  I got many syntax errors because I'm not familiar with the symbols and code for entering functions and commands.
and you can create a diagonal matrix by entering diag([1 2 3])
it looks like this.


If I enter:
    diag([1 2 3])
y=x;
plot (x,y)


then it plots the graph of y=x.
ans =


But when I enter:
  1  0  0
y=x^2;
  0  2   0
plot (x,y)
  0  0  3
 
it says: error: For A^B, A must be square.
 
I'm confused, but Hopefully I'll figure out more in the future.
 
I spent 1 hour installing this program and trying to figure it out.
