reachInner algorithm example: problem with the mptPolytope contructor

[dfcaporale]

Hi,

My name is Daniel, and I am taking my first steps heading for using the reachInner algorithm from your package. Trying to run the example from Sec. 4.1.2 from the CORA Manual, I got stuck with an issue. After debugging the code a little bit, I noticed that the problem is in the call to the mptPolytope constructor (in this line).

Here is the stack trace:

>> C = [1 0 -1 0 1; 0 1 0 -1 1]';
>> d = [3; 2; 3; 2; 1];
>> poly = mptPolytope(C,d);
Undefined function 'polytope' for input arguments of type 'double'.

Error in mptPolytope (line 73)
                obj.P=polytope(varargin{1},varargin{2});

Am I doing something wrong?

Thanks in advance, and congratulations on your code!

Hi Daniel,
Thanks for your kind words!

Did you install the mpt toolbox as explained in Section 1.3 of the CORA manual?

Hi @wetzlingerm,

You are right. I'd previously installed the required packages manually and added the paths to MATLAB, but something else needed to be set appropriately.

Now it's working perfectly. This time I did it with the script install_mpt3.m and tested with test_requiredToolboxes, and everything is fine.

Thank you so much for your quick reply!
