Symbolic Vector Library 1.1   (details) 48 ENG   7KB/6KB
SYMVEC (SV) is a User RPL-written library of symbolic vector functions for use in mathematics and the sciences. Support is given for Cartesian, Cylindrical, and Spherical polar coordinates, as well as general orthogonal coordinates (whose definitions are supplied by the user). The current coordinate mode is sensed automatically by the library, and the user may override the sensing and force execution in a chosen coordinate system. The SV functions are, for the most part, usable in algebraic expressions (although their inputs may not be -- the intention is for simplification of programming).
