Question about Matlab compatibility

[David]

Hi!

 

I'm trying to learn Matlab/Octave from a book about Matlab. I understand there are some differences in the plotting functions, but there are some commands in the Matlab book relating to solving symbolic equations which don't seem to exist in Octave v3.0.1. For example:

 

syms (use the 'sym' command instead?)

dsolve

solve

limit

 

Here's one simple example from the book:

 

>> syms x

>> limit(x + 5,3)

 

ans =

 

8

 

Any suggestions? Is there a package I need to install to provide these commands?

 

Thanks.
