Follow-up Comment #2, bug #53111 (project octave):
Thank you, this is significantly better.
matlab must internally simplify prior to printing to the command window.
So for me this is an easy fix.
x_d_a=simplify(diff(x,a))
I think this can be closed, and I will just do the above from now on.
---------------------------------------------
I agree with your thoughts about compatibility, since placing the same values
in the equation will produce the same final solution.
However, in coursework a professor (or computer) may just see the equations
are different, and not award credit.
---------------------------------------------
For some reason I thought if I could expand then everything would go away. So
I tried.
help expand
error: help: 'expand' not found
I did not think of:
help simplify
error: help: 'simplify' is a method of class 'sym'; it must be called with a
'sym'
argument (see 'help @sym/simplify').
Please read <http://www.octave.org/missing.html> to learn how you can
contribute missing functionality.
