How to run matcont in Mac computer

I'm using a Mac computer, and I installed Matlab R2013a, also downloaded the latest matcont profile, but it just cannot run the matcont. Is there anyone who has the same situation likes me? I really hope I could get a help here! I appreciate. Thank you!

What happens when you try?

This is what made it work for on my computer, essentially one changes 10.7 to 10.8 in the mexopts.sh file in four places...:

AndreaS- could you please help me. I followed the link you suggested and went through all the steps: I have Xcode 5.0.2 and MATLAB R2013b on my new MacBook Air with OS X Mavericks (10.9.1). After I went through the steps outlined in the above link and then select the matcont directory and type in: matcont in the command line I get: Undefined function or variable 'matcont'!!!!!!! please could you tell me what exactly you did to get it to work? I have never used matlab or matcont on a mac and this is the first time I'm using a Mac too.

never mind i got it to work!

I'm having the same problem. I'm trying to install MatCont (5p3) build on my iMac running OS X Mavericks. I have Xcode installed correctly but when I run the 'init.m' file in the MatCont package I get the following error in the command window:

EDU>> init xcodebuild: error: SDK "macosx10.7" cannot be located. xcrun: error: unable to find utility "clang", not a developer tool or in PATH

    mex: compile of ' "BVP_LC_jac.c"' failed.

Error using mex (line 206) Unable to complete successfully.

Error in init (line 35) mex -largeArrayDims -O BVP_LC_jac.c;

It looks as if the MatCont package is looking for a specific Xcode build "macosx10.7".

Did you try to open the new Xcode already in order to download the required compiling/sdk tools? I had to do that in order before being able to compile anything.

I am having the same problem. I recently upgraded to OSX 10.9 Mavericks, I'm using Matlab R2013a on an iMac. It's a trial version, but according to the mathworks help desk it shouldn't matter. What is the new Xcode - do I need to download some additional software to use the MATCONT package in Matlab?

Below are the error messages that I am getting when trying to use MATCONT:

Trial>> mex -setup

    Options files control which compiler to use, the compiler and link command
    options, and the runtime libraries to link against.

    Using the 'mex -setup' command selects an options file that is
    placed in /Users/abruder/.matlab/R2013a and used by default for 'mex'. An options 
    file in the current working directory or specified on the command line 
    overrides the default options file in /Users/abruder/.matlab/R2013a.

    To override the default options file, use the 'mex -f' command
    (see 'mex -help' for more information).

The options files available for mex are:

1: /Applications/MATLAB_R2013a.app/bin/mexopts.sh : 
    Template Options file for building MEX-files

0: Exit with no changes

Enter the number of the compiler (0-1): 1

After installing Xcode, the error message changes slightly, but the problem persists:

Trial>> mex -setup

    Options files control which compiler to use, the compiler and link command
