%CODER.TARGET Determine the current code-generation target

%

%   CODER.TARGET('TARGET') determines if the specified TARGET is the

%   current code generation target. The following TARGET values may be

%   specified:

%       MATLAB      True if running in MATLAB (not generating code).

%       MEX         True if generating a MEX function.

%       Sfun        True if simulating a Simulink model.

%       Rtw         True if generating a LIB, DLL or EXE target.

%       HDL         True if generating an HDL target.

%       Custom      True if generating a custom target.

%

%   Example:

%       if coder.target('MATLAB')

%           % code for MATLAB evaluation

%       else

%           % code for code generation

%       end
