Limitations and Restrictions on Current MATLAB Compiler (version 2.0.2)

Cannot compile :

Script M-files
Functions that are MEX functions
M-files that use objects
M-files containing eval or input
Inline functions (since they are implemented via eval
Built-in MATLAB functions such as lu cannot be compiled since they are not available as M-files. They are, however, stored in libmatlb.so and hence are available to you.
Restrictions on the use of load, save
load(filename); % OK load(filename, 'x', 'y'); % OK load(filename, x, y) % NOT OK
