Internal Interface Functions

* output. The void interface function specifies zero

* output arguments to the implementation version of the

* function, and in the event that the implementation

* version still returns an output (which, in MATLAB, would

* be assigned to the "ans" variable), it deallocates the

* output. This function processes any input arguments and

* passes them to the implementation version of the

* function, appearing above.

C++ Interface Functions

TheC++interfacefunctions processanyinputarguments and pass them to the

implementation version of the function.

Note In C++, the mlxF interface functions are also C functions in order to

allow the feval interface to be uniform betwe en C and C++.

mlx

Interface Function

The Com p ile r always generate s the mlxF interface function, which is used by

feval. At times, the Compiler needs to use feval to perform argument

matching even if the user does not specifically call

feval. For example,

x = cell(1,5);

y = {1 2 3 4 5};

[x{:}] = deal(y{:});

void mlfVFoo(mxArray * x, mxArray * y) {

mxArray * a = NULL;

mxArray * b = NULL;

mlfEnterNewContext(0, 2, x, y);

a = Mfoo(&b, 0, x, y);

mlfRestorePreviousContext(0, 2, x, y);

mxDestroyArray(a);

mxDestroyArray(b);

}
