1 Introducing the MATLAB Compiler
1-10
Figure 1-1: Developing MEX-Files
MATLAB users who do not have the MATLAB Compiler must write the source
code for MEX-files in either Fortran or C. External Interfaces/API in the
MATLAB documentation explains the fundamentals of this process. To write
MEX-files, you have to know how MATLAB represents its supported data types
and the MATLAB external interface (i.e., the application program interface, or
API.)
If you are comfortable writing M-files and have the MATLAB Compiler, then
you do not have to learn all the details involved in writing MEX-file source
code.

Shaded block is user-written code.
Shadowed blocks are MathWorks tools.
Unshaded blocks are MATLAB
Compiler-generated code.
Dotted block is C/C++ compiler-generated
executable.
