Limitations About What May Be Compiled

Note Se e “ Un suppo rte d Functions” on page 9-8 for a complete list of

functions that cannot be compiled.

MATLAB Code

MATLAB Compiler 4 supports much of the functionality of MATLAB.

However, there are some limitations and restrictions that you should be

aware of. This version of MATLAB Compiler cannot create interfaces for

script M-files (See “Converting Script M-Files to Function M- Fil es” on page

5-19 for further details.)

Fixing Callback Problems: Missing Functions

When MATLAB Compiler creates a standalone application,itcompilesthe

M-file(s) you specify on the command line and, in addition, it com piles any

other M-files that your M-file(s) calls. MATLAB Compiler uses a dependency

analysis, which determines all the functions on w hich the supplied M-files,

MEX-files, and P-files depend. The dependency analysis may not locate a

function if the only place the function is called in your M-file is a call to the

function either

• In a callback string

• In a string passed as an argument to the

feval function or an ODE solver.

MATLAB Compiler does not look in these text strings for the names of

functions to compile.

Symptom

Yo ur application runs, but an interactive user interface element, such as

a push button, does not work. The compiled application issues this error

message:

An error occurred in the callback: change_colormap

The error message caught was : Reference to unknown function

change_colormap from FEVAL in stand-alone mode.
