Composition of Matrix Multiplication

Composition of Matrix Multiplication means More than one linear transformations applies to a graph one by one.

**Although you can see two matrices multiplying together as a transform applying to a graph.
But actually sometime you can see it in slightly different perspective.**

Refer to 3Blue1Brown: Matrix multiplication as composition

So extend from the equation above, we know that the transformation rules could Unite together as one and then apply it to the graph.
And here it comes, MATRICES MULTIPLICATION COULD ALSO REPRESENT TRANSFORM RULES UNITE TOGETHER AS A RESULT RULE, RATHER THAN ONE RULE WORK ON A GRAPH.

Order matters!
