ChExcel is a
Microsoft Excel add-in. It embeds Ch (a C/C++ Interpreter)
into Excel
using Embedded Ch.
ChExcel allows users to do C scripting, plotting and numerical computing
from Excel worksheets and
Visual Basic for Applications (VBA).
With ChExcel, Excel speadsheets can be
manipulated through C/C++ scripts.
The data can be
easily exchanged between Ch and Excel.
The architecture of how ChExcel embedding Ch into Excel is
illustrated in the figure below.
Excel is a user interface to Ch, allowing the
user to utilize Ch statements, functions,
programs, toolkits, and packages from Excel spreadsheets and VBA.
The communication
between Excel and Ch is controlled by a few simple ChExcel functions,
keeping the interface simple and easy to use.
The Excel spreadsheet below is an
example of interface between Excel and Ch using ChExcel functions.
The Excel spreadsheet dialogbox.xls
is manipulated by a script dialogbox.ch.
This is one of examples included in the distribution of
ChExcel.
