MATLAB: Do I get this error since there is only one function

duplicate nameerrorfunctionsMATLAB

Hello

I get the below error

Error: File: SegmentBone.m Line: 7 Column: 18
Function with duplicate name "SegmentBone" cannot be defined.

If I use

which SegmentBone

It will give me the correct function "SegmentBone.m" in the working folder. There is no other function having exactly the same name. There are other functions with the name "SegmentBoneDP.mexmaci64" for instance or "SegmentBoneDP.cpp"

But their names are not identical. Thus, they are considered different names. Why do I get the error then?

This happens when a script file with that name contains a function definition with the same name. Which can also happen in what you thought was just a function definition file if you accidentally put commands before the function, such as accidental typing or such as a clc or clear statement.

Looks like you have a mismatch with variable types, probably an older piece of code that you are trying to compile on a newer MATLAB version. E.g., the code probably has this definition:

const int *DimsBness;

when it should be this:

const mwSize *DimsBness;

And you probably have something like this:

const int *dims;

or this

int dims[] = {2,3}; /* or whatever */

when it should be this:

const mwSize *dims;

or this

mwSize dims[] = {2,3}; /* or whatever */

Simply update the code with the required types to fix these errors.

Your SegmentBoneDP.cpp file is the source code.

If you need something that converts C++ code into MATLAB code, then you are using the wrong product family. There is no known program that converts C++ code into MATLAB code.

"The point is that I don't know the number and type of inputs the function requires since I cannot open it to see it. "

You read them out of the C++ source code.

    Bness = (double *)mxGetData(prhs[0]);
    double *pF0,*pF1,*pBth,*pJumpConst;
    pF0 = (double *)mxGetData(prhs[1]);
    pF1 = (double *)mxGetData(prhs[2]);
    pBth = (double *)mxGetData(prhs[3]);
    pJumpConst = (double *)mxGetData(prhs[4]);

The first parameter is Bness, and is a 2D double array.

The second parameter is F0, and it is a double scalar. It appears to be used as a weight or smoothing factor

The third parameter is F1, and it is a double scalar. It appears to be used as a weight or smoothing factor

The fourth parameter is Bth, and it is a double scalar. It is a threshold between bone and no bone.

The fifth parameter is JumpConst, and it is a double scalar. It appears to be some kind of penalty for moving from bone to no bone.

The output is an array the same size as Bness, and it is a real double 2D array.
