PanVectorXd

PanVectorXd is a data structure and algorithm primarily used in computer graphics and computational geometry for representing and manipulating n-dimensional vectors. It is designed to be flexible, allowing for vectors of varying dimensions at runtime, hence the "Xd" designation. The "Pan" prefix suggests a broad or universal application across different domains.

Key features of PanVectorXd often include dynamic resizing of the vector's dimension, efficient memory management for potentially large vectors, and a suite of overloaded mathematical operations such as addition, subtraction, dot product, and cross product (where applicable based on dimension). Implementations typically focus on performance, especially when dealing with numerous vector operations in simulations, transformations, or geometric calculations. The underlying storage mechanism might vary, but it often employs contiguous memory allocation for speed.

PanVectorXd finds applications in areas like physics engines for game development, scientific simulations requiring multidimensional data representation, robotics for kinematic and dynamic analysis, and any field that necessitates the manipulation of vectors beyond the common 2D or 3D cases. Its adaptability makes it a valuable tool when the exact dimensionality of a problem is not fixed beforehand or when dealing with abstract mathematical spaces.
