Central difference method equation

WebIn numerical analysis, the FTCS (Forward Time Centered Space) method is a finite difference method used for numerically solving the heat equation and similar parabolic partial differential equations. [1] It is a first-order method in time, explicit in time, and is conditionally stable when applied to the heat equation. WebFirst Central Difference Method, what is the formula and what is another name for it? Definition Allows us to match kinematic data based on positions of the segment endpoints from each frame within a time interval.
