Error using legacy_code (doubleIt Example)

Hey there, ive got some problems. I was rebuilding the example "Integrate C Functions Using Legacy Code Tool" and got some errors after "legacy_code('sfcn_cmex_generate', def);".

Here is my code:

---

doubleIt.c:

#include "doubleIt.h"

double doubleIt(double inVal)

{

    return(2*inVal);

}

---

doubleIt.h:

#ifndef DOUBLEIT_H

#define DOUBLEIT_H

double doubleIt(double inVal);

#endif

---

Matlabcode:

def = legacy_code('initialize')

def.SourceFiles = ('doubleIt.c');

def.HeaderFiles = ('doubleIt.h');

def.SFunctionName = 'ex_sfun_doubleit';

def.OutputFcnSpec = 'double y1 = doubleIt(double u1)';

legacy_code('sfcn_cmex_generate', def);

---

Errors after typing "legacy_code('sfcn_cmex_generate', def)":

Error using lct_pValidateStructure (line 44) The field "HeaderFiles" is of class "char" and must be of class "cell"

Error in C:\Program Files\MATLAB\R2013a\toolbox\simulink\simulink\+legacycode\@LCT\LCT.p>LCT.LCT (line 43)

Error in legacy_code (line 87) [varargout{1:nargout}] = legacycode.LCT.legacyCodeImpl(action, varargin{1:end});

How do i fix it? :X

The documentation uses curly braces (which defines cell-arrays) to define the SourceFiles and HeaderFiles fields (you are using regular parentheses):

...
def.SourceFiles = {'doubleIt.c'};
def.HeaderFiles = {'doubleIt.h'};
...

Thank you.

I've observed this too, later. ;)
