State Vector

A state vector is a mathematical concept used in various fields, particularly in physics and engineering, to represent the complete state of a system at a specific time. Think of it as a list that describes all important characteristics of that system, such as its position, velocity, and energy. Each item in the vector gives you a piece of information, and together they provide a comprehensive snapshot of the system. This helps scientists and engineers analyze and predict how the system will behave over time, akin to a detailed report showing everything necessary to understand a situation.
