MATLAB Compiler Generated Interface Functions

Note For C shared libraries, MATLAB Compiler generates the mlx and mlf

functions as described in this section. For C++ shared libraries, M ATLAB

Compiler generates the

mlx function the same way it does for the C shared

library. However, MATLAB Compiler generates a modified

mlf function with

these differences:

• The

mlf before the function name is dropped to keep compatibility with R13.

• The arguments to the function are

mwArray instead of mxArray.

mlx Interface Function

The function that begins with the prefix mlx takes the same type and number

of arguments as a MATLAB MEX-function. (See the External Interfaces

documentation for more details on MEX-functions.) The first argument,

nlhs,

is the number of output arguments, and the s econd argument,

plhs,isa

pointer to an array that the function will fill with the requested number of

return values. (The “

lhs” in these argument names is short for “left-hand

side” -- the output variables in a MATLAB e xpression are those on the

left-hand side of the assignment operator.) The third and fourth parameters

are the number of inputs and an array containing the input variables.

void mlxSierpinski(int nlhs, mxArray *pl hs[] , int nrhs,

mxArray *prhs[])

mlf Interface Function

The second of the g enerated functions begins with the prefix mlf.This

function expects its input and output arguments to be passed in as individual

variables rather than packed into arrays. If the function is capable of

producing one or more outputs, the first argument is the number of outputs

requested b y the caller.

void mlfSierpinski(int nargou t, mxArr ay** x, mxArray ** y,

mxArray* iterations, mxArray* draw)
