Parametric Solutions

Definition

Parametric solutions refer to a way of expressing the solutions of a system of equations in terms of one or more parameters. This approach allows for a more flexible representation of infinite solutions, particularly when dealing with linear systems where there are free variables. Using parameters can simplify complex problems in data science, making it easier to model and interpret relationships within data.
