Solutions for Scientific Computing in Engineering and Science
Ch is the simplest possible solution to
2D/3D plotting and numerical computing
within the framework of C/C++
There are numerous problems in engineering and science
that have to be solved with scientific numerical computing
and visualization. Ch is an ideal computing environment
for engineers and scientists
to solve their challenging problems productively.
Ch contains salient features with simplicity of Fortran
and mathematical software packages such as MATLAB® and
Mathematica® to ease engineering and scientific numerical computing.
If you are familiar with mathematical software packages
MATLAB® and Mathematica®, you may find the
following information helpful in understanding the capabilities of Ch.
Ch has been developed to meet most computing needs for engineers
and scientists.
Engineers and scientists select Ch as their solution for the following
reasons:
 Power
As a superset of C with classes in C++, Ch
has a very rich set of features for scientific numerical computing and
visualization, including all new features for numerical computing in C99 such as IEEE floatingpoint arithmetic, complex numbers, variable length
arrays (VLAs), and generic functions.
Ch is the only computing environment in existence that can perform numerical computing with consistent numerical results
under the IEEE floatingpoint arithmetic in the entire real domain and complex domain using an extended complex plane for a
Riemman sphere.
Unlike special mathematical software packages, Ch conforms to many
industry standards. For example,
wide characters is supported in Ch for internationalization.
You can develop scientific numerical computing applications with
LAPACK, 2D/3D plotting, CGI, OpenGL, ODBC, GTK+, XWindows and Motif.
 Cost saving
Prior to Ch,
one may use C/C++ for general algorithm development and graphical
packages or Excel for display and visualization;
or use expensive mathematical
software packages such as MATLAB and Mathematica for rapid prototyping,
then generate C/C++ code for final production.
Any change to machine geneated C/C++ code has to be propagated
from the code written in MATLAB or Mathematica.
With Ch, all development can be accomplished in a single language
environment. This not only reduces the cost for purchase of multiple
software packages and compilers from different vendors,
but also the cost for
development and maintanence of code with higher productivity.
 Efficiency and easy of use
Ch is a very highlevel language (VHLL) environment. It can conveniently glue different applications and components together. Ch encourages code reuse.
Thousands of lines of C/C++ code for numerical computing can be accomplished
with only a few lines of Ch code.
Application programs are easy to develop and maintain.
Extensive numerical features with advanced library
and
graphical plotting
dramatically simplify algorithm development and visualization.
Computational arrays
allow matrices to be manipulated as
firstclass objects
so that mathematical formulas such as linear equation b = A*x can be written
verbatim in Ch. The user does not need to worry about the underlying optimization
with fast and accurate numerical algorithms.
Ch is especially suitable for development of Webbased
applications in engineering and science as shown in
online scientific numerical computing and visualization.
 Third Party Solutions
An increasing number of Ch toolkits and third party packages are supported.
Ch Control Toolkit, Ch NAG Statistics Package, Ch OpenCV package, etc.
make Ch a powerful platform for engineers and scientists.
