Assign Octave matrix elements to variables

Question

I am trying to do something like this in Octave:

Assign some variables to a matrix, do some operation on the matrix and then assign the members of the matrix back to the variables, e.g:

x=1; y=2; d=[x y]; d=(d.^2)+1; [x y]=d;

However, this does not work and only x is assigned the complete matrix. Is there a way to achieve this?

You can index into d.

x=d(1); y=d(2);

or convert d to a cell array using num2cell and then to a comma-separated list and then deal it.

[x, y] = deal(num2cell(d){:});

I recommend the first method.

The second way is what I was looking for (although I don't completely understand it). Thank you!

One-liners are overrated. Anyway, try doing it in parts and see the output for each part. Let me know if you still find anything unclear
