What are transformations in maths?
A transformation is how you move a shape from one place to another. For example rotations, translations and reflections are all ways of moving a shape.
Laplace' is known for transformations in math; as in a Laplace Transformation. Transformations are used extensively in matrix models in general equilibrium theory and econometrics such as Dominate Diagonal transforms. That is where I reached my level of incompetency; fond memories. See: Lionel McKinsey, Economic Theory and Matrices with Dominate Diagonals
A Mapplet is a reusable object that represents a set of transformations. It allows you to reuse transforamtion logic and can contain as many transformations as you need. A Mapplet can contain transformations, Reusable transformations and shortcuts to transformations. The difference between a Mapplet and a Reusable transformation is - A Mapplet is a set of transformations where as a reusable transformation is single transformation. regards, firstname.lastname@example.org, 7411005677
