Greetings,

I am debugging others' codes. In Polyhedron.m file row 521, it is a sentence:

if isempty(obj.He_int), obj.He_int = zeros(0,d+1); end

I found before this sentence was executed, obj.V was not defined as:

But after this sentence was executed, obj.V was calculated and got a matrix:

As you see, the sentence did not call obj.V directly but it did change obj.V. Could you explain to me what happened here? And how can I find the codes that changed obj.V. I think that is the bug I am looking for.

Related source codes are attached.

Thank you!

obj.V is a Dependent property.
