Here are practical algorithms -- tested, explained, and written in C -- that scientists and engineers can use with little or no modification to solve the mathematical problems they encounter every day. The sure solution to faster, easier, and more accurate work.

A collection of time-saving C routines for direct application or use in larger, customized programs. A companion to the author's 1989 work. Methods covered include: multigrid methods for partial differential equations, conjugate-gradient and block matrix methods for sparse systems, Bresenham's line-drawing algorithm, contour plotting.

Basically a collection of mathematical function source code impelementation.
