What does IPQ mean?

The full form of IPQ is Inverse Piecewise Quadratic functions. Also known as piecewise functions, these are the functions that are defined by several sub-functions. Each sub-function is applied to different intervals in the domain of the function.

The piecewise representation of a function is a way of expressing a function instead of being a characteristic of the function. When a domain can be divided into several intervals, the piecewise property of a function holds true and can be applied.

Interpretation of IPQ

These functions are defined using a general notation used for functions. It consists of the body which is an array of functions and subdomains. For a function to be termed as a piecewise function, the subdomains of the function must be intervals that may be degenerated or unbounded in nature. In unbounded intervals, the number of subdomains needs to be only locally finite whereas, for the bounded intervals, it should be finite.

Example of Piecewise functions

Consider a piecewise definition for the absolute function. It states that for values that are less than zero, the function should take a negative value. This negates the sign of the negative number making it into a positive number. For values that are greater than zero, the function stays the same as there need not be any change. For any input value for the piecewise function, the relevant subdomain must be chosen so that the correct function brings out the correct output value for the particular input value.

Applications of IPQ

Piecewise functions have been found in several models of the human visual system in applied mathematics analysis. In these systems, the human images are first perceived as having smooth regions that have been separated by edges. To provide approximations of these models, shearlets have been used as a means of the representation system.
