Why C and Matlab?
Why C?
Powerful and portable computer language
Most well known processors be programmed with C
Simple to program
Free!! =D
Why Matlab?
Most powerful programming tool for Engineering
Used in many areas
From Aerospace Industry To Financial companies
No rivals, but expensive

Adding a Source File to the Project
Click
The .c filename extension tells Visual Studio to compile this file
as a C program (not C++).

Running Without the IDE
Open a Windows Explorer window and navigate to the project directory.
Your directory structure will be different, but you should have a
project directory called “hello” under “Visual Studio 2005\Projects”

22
Running Without Visual Studio
Within the project directory, open the debug folder.
We can double
click here to run
the program
independently of
the IDE.
Here is the exe file.

Running Without Visual Studio
We can also run the program from the
command prompt.
Copy the exe file into a convenient directory
(e.g. C )
Open a command window
cd to the directory
Type the command: hello
