thumb|300px|The gradient, represented by the blue arrows, denotes the direction of greatest change of a scalar function. The values of the function are represented in greyscale and increase in value from white (low) to dark (high).
AI overview
A gradient is a mathematical tool that shows which direction a quantity is changing most steeply at any given point, like how a slope indicates the steepest way up a hill. It matters because it helps scientists and engineers understand how things like temperature, pressure, or other quantities vary across space, which is essential for solving real-world problems.
