Hi,Najmeh, I met the same question as you. And I solve it in this way: I use Matlab 2018b，and in MATLAB --> HOME -->Set Pat, choose the path as to ***\toolbox\symbolic\symbolic and it works.

If you look under the Maple installation directory you should be able to find a script or app to uninstall the Maple Toolbox. The exact name depends on your operating system. (I cannot check mine for a few hours)

If you are using the Maplesoft provided Maple Toolbox (for MATLAB), then:
At least on OS-X, under the MATLAB installation directory (MATLAB command matlabroot will show you its name), there is an Uninstall_MapleToolbox folder that contains an uninstall program. For example on my OS-X system it is
/Applications/MATLAB_R2014a.app/Uninstall_MapleToolbox/uninstall.app

Hi Xianjie,
MUPAD engine replaced Maple engine starting from MATLAB version R2007b+ and hence option was provided to switch to Maple engine if one has compatible version of a Maple software installed.
Entering the following command at the MATLAB command line would bring up a GUI for making your choice:
>>symengine
However, this option was made available in MATLAB R2007b+, R2008a+, R2008b, R2009a and R2009b. Starting from MATLAB version R2010a, the option to switch to Maple engine was removed and MUPAD was made the default and the only supported engine.
Since you mentioned that you were able to switch to Maple engine successfully I assume that you are using one of these MATLAB version - R2007b+, R2008a+, R2008b, R2009a and R2009b. If so, you can switch to the default MUPAD by using command 'sysengine' as shown above.

It is best to execute the file: >>symengine.p
from (your MATLAB installed directory): \...\toolbox\symbolic\symbolic
Otherwise, it does not work.

One line solution: MATLAB --> HOME -->Set Path --> Default --> Save.

install "Maple Toolbox (for MATLAB)" provided by Maplesoft. When you do that, the maple related directory will be put on the matlab path earlier than the matlab symbolic toolbox, so functions such as syms will get resolved by the maple version.
Note: when you go to install maple if it detects that matlab is installed it asks you if you want the appropriate toolbox installed for MATLAB, so it is common to not need to specifically run the installer as the sequence would run the installer on your behalf.

You just need to remove the Maple's toolbox folder from the Matlab Saved Paths so that when you call a function, it doesn't use the Maple toolbox.
