If you are not familiar with using the directories that @tomleslie referred to (which can interfere with your installation of Maple if modified incorrectly), you can also install an add-on package to a specified user library folder:

If you have previously added a custom user library path to 'libname', please copy the library file “%PackageName%.mla” to that folder. If you have not, you may add that user library folder by doing the following:

1. Copy “%PackageName%.mla”  to a user library folder. If you do not have a user library folder, simply create a folder for your Maple library files. This folder may be located anywhere on your computer, though a suggested path is to create a new folder called MapleLib in your "home directory" and place the files there. To find your home directory in Maple, use kernelopts( homedir ) ; For more information, see the kernopts help page.
    
2. Open your Maple initialization file. See the initialization file help page for details on how to create and configure these initialization files.
    
3. Add the line: libname := libname, "PathToUserLibraryFolder” : For example, to add the path to your "MapleLib" folder under your home directory use libname := libname, cat( kernelopts( homedir ), kernelopts( dirsep ), "MapleLib" ) :
    
4. Save your Maple initialization file and restart Maple.

I get very different results when I run your code.  Also, even with the iteration limit set very high, I can't seem to escape the iterations error.  Can you post your full worksheet, and confirm which version of Maple you're using?

You seem to get a RoofOf-based solution for most fixed w (see attached).  This would indicate that the nature of the solutions are too varied for various values of alpha, A, J, and L to communicate with any degree of accuracy.  Do you have any information regarding the values of these variables?

If this FAQ page doesn't help, please send a screen shot of the window that keeps appearing to support@maplesoft.com.

Yes, and in that post, the first warning refers to a line in the matlabrc.m file.  The line numbers were not included in your post, so I don't know whether those are the lines just before it, just after it, etc. If you're confident that you've checked all relevant lines near 257 (the only line that I can see has been referenced), please send us the file (support@maplesoft.com) so that we can take a closer look at it.  I also recommend trying

export DYLD_LIBRARY_PATH="%MAPLE-PATH%":$DYLD_LIBRARY_PATH

based on the format of the warnings you are seeing.

@daroloson just to clarify, is this the issue you are experiencing?  If so, does the solution they outline help?

@daroloson thanks for the info.  In the terminal, please try executing

export DYLD_LIBRARY_PATH="%MAPLE-PATH%":$DYLD_LIBRARY_PATH

anyway and see if it helps.  If not, since the connection you are trying to make is coming from Matlab, you may need to contact MathWorks for assistance.  Feel free to send us the commands that you are trying to enter in Matlab so that we can try to see if anything is out of place.

@daroloson Thanks for the additional information.

The value ' ' is not valid for the environment variable MATLAB_SYMBOLIC

Hi, thanks for posting on MaplePrimes. Since Maple 2017.0 was released after MATLAB R2017a, you may need to wait for an update from MathWorks, but can you please be more specific about how the link isn't working, and tell us which operating system you're using?  Be sure to include screen shots of any error messages that you encountered when trying to complete the link - feel free to contact us directly at support@maplesoft.com.

Thanks,
