Create a test case for interactive testing.

import matlab.unittest.TestCase
import matlab.unittest.constraints.IsEmpty

testCase = TestCase.forInteractiveUse;

Verify that an empty character vector satisfies the IsEmpty constraint.

testCase.verifyThat('', IsEmpty)

Interactive verification passed.

Assert that a vector is not empty.

testCase.assertThat([13 42], ~IsEmpty)

Interactive verification passed.

Verify that a matrix with a dimension of length zero is empty.

testCase.verifyThat(rand(2, 5, 0, 3), IsEmpty)

Interactive verification passed.

Assert that an empty object satisfies the IsEmpty constraint.

testCase.assertThat(MException.empty, IsEmpty)

Interactive assertion passed.

Verify that a cell array containing an empty numeric array is empty.

testCase.verifyThat({[]}, IsEmpty)

Interactive verification failed.

---------------------
Framework Diagnostic:
---------------------
IsEmpty failed.
--> The value must be empty.
--> The value has a size of [1  1].

Actual Value:
        {[]}

The cell array is not empty, even though the only thing it contains is an empty array.
