Modified Test Expectations

Pull Request: Resolve Issue #1309

This pull request addresses and resolves issue #1309 by modifying test expectations in intersect.m to handle empty input cases correctly.

Description of Changes

The approach was to adjust the expected output for a specific test case that was previously failing due to handling symbolic arrays intersected with an empty set.

Code Before

%!test
%! % empty input
%! A = sym([1 2]);
%! C = intersect(A, []);
%! assert (isequal (C, sym([])))

Code After

%!test
%! % empty input
%! A = sym([1 2]);
%! C = intersect(A, []);
%! assert (isequal (size(C), [1, 0]))

In this update, the assertion now checks that C has a size of [1, 0], aligning with the expected behavior for symbolic arrays when intersected with an empty set.

Test Results

After making these changes, all tests for intersect.m have successfully passed, confirming the issue has been resolved:

@cbm755 , could you please review this PR when you have a chance? Thank you for your time!

Would assert (isempty (C)) work?

[cbm755]

(advantage is test would pass on both new and old sympy)

[Sonu0305]

Would assert (isempty (C)) work?

Yes, this too is likely to work.

Ok, please make that change too then and we'll get this merged.
