I want to verify that a method was called twice with inputs to be verified

I want to make sure that

cls.myfunc('first')
cls.myfunc('second')

occurred.

Example:

%setup
testCase = matlab.mock.TestCase.forInteractiveUse;
[mockedCls, behavior] = testCase.createMock('AddedMethods', 'myfunc');
%run
mockedCls.myfunc('first')
mockedCls.myfunc('second')
%verify -> THIS DOES NOT WORK
testCase.verifyThat([
    behavior.myfunc('first')
    behavior.myfunc('second')], WasCalledInCorrectOrder)

The verification code above is just an example. How would you do such a verification?

I know this reply is coming very late, but in case it's still helpful, this is now possible in R2019b using the Occurred constraint:

import matlab.mock.constraints.Occurred;
%setup
testCase = matlab.mock.TestCase.forInteractiveUse;
[mockedCls, behavior] = testCase.createMock('AddedMethods', "myfunc");
%run
mockedCls.myfunc('first')
mockedCls.myfunc('second')
%verify - this passes:
testCase.verifyThat([
    behavior.myfunc('first')
    behavior.myfunc('second')], Occurred("RespectingOrder",true));
%verify - this fails:
testCase.verifyThat([
    behavior.myfunc('second')
    behavior.myfunc('first')], Occurred("RespectingOrder",true));
