Why we use == in MATLAB?

Tips. When comparing handle objects, use == to test whether objects have the same handle. Use isequal to determine if objects with different handles have equal property values.

What is the difference between and %% in MATLAB?

One percent sign ( % ) is used for commenting lines. Two percent signs ( %% ) have a different purpose: they are used for dividing your code into sections, which can be run independently. This allows easier debugging.
