MATLAB Introduction and the Working Environment - MATLAB Graphical Programming - page 10

In terms of the integration of the MATLAB code with other languages and applications, MATLAB provides
functions to integrate code C and C++, Fortran code, COM objects, and Java code in your applications. You can call
DLLs and Java classes and ActiveX controls. Using the MATLAB engine library, you can also call MATLAB from C,
C++, or Fortran code.
For distribution of applications, you can create algorithms in MATLAB and distribute them to other users
of MATLAB M file using the MATLAB Compiler (available separately). Algorithms can be distributed, either as
standalone applications or as modules in software for users who do not have MATLAB. Additional products can be
used to turn algorithms into a software module that can be called from COM or Microsoft Excel.
1.2 MATLAB Working Environment
Figure 1-10 shows the screen used for entering the program, which is the primary MATLAB work environment.
