Issue
Hi, I have some concerns with this statements:
obj1=MultiMatrix(sparseTimes(obj1.Data,obj2.Data));
actually it will give problems later when the object obj1 have more properties, from instance a frequency axis. I think the right thing to do is
obj1.Data =sparseTimes(obj1.Data,obj2.Data);
In that way any other property of obj1 is preserved.
