Ansatz




For example, given a Set of experimental data that looks to be Cluster ed about a line, a linear ansatz could be made to find the Parameter s of the line by a Least Squares curve fit. Variational Approximation methods use ansatzes and then fit the parameters.

Another example of ansatz is to suppose the solutions of a homogeneous linear Differential Equation and Difference Equation to have, respectively, exponential and power form.
