Constants:

The variables are used to store values which can change, or that are not known ahead of the time. Most of languages also have the capacity to store constants that are values which are known ahead of the time, and cannot possibly change. An illustration of a constant value would be pi, or π, that is 3.14159.... In a MATLAB, there are functions which return some of these constant values. Some of these involve:
