Ch Professional Edition 3.5

Ch is a superset of C interpreter for numerical computing. It has very rich features for scientific numerical computing
and visualization, including all new features for numerical
computing in the latest C standard called C99 such as IEEE
floating-point arithmetic, variable length arrays (VLAs), complex
numbers and type generic mathematical functions.

It also supports computational arrays and C LAPACK for
linear algebra and matrix computations.


Ch has built-in 2D/3D graphical plotting support, generic mathematic
functions and computational arrays for linear algebra and matrix
computations, and advanced high-level numerical functions
for linear systems, differential equation solving, integration,
non-linear equations, Fourier analysis, curve fitting, etc. For
example, linear system equation b = A*x can be written verbatim in Ch.
