2012年2月，maple 16出炉！
2012年4月，下到破解版！
安装过程中，检测到MATLAB R2010B（即MATLAB 7.11）！
安装完成后，自动创建环境变量MATLAB_SYMBOLIC，其值为：maple，此时，matlab符号计算引擎为maple。若将该环境变量值改为matlab，则符号计算引擎为 Symbolic Math Toolbox（现在用的是mupad符号引擎）。

MATLAB_SYMBOLIC - Setting the default symbolic toolbox
The default symbolic toolbox is the version of the symbolic toolbox
used by MATLAB when it is launched using the standard start scripts or
shortcuts. The default symbolic toolbox is determined by the
environment variable
MATLAB_SYMBOLIC
which must be set to either 'maple' or 'matlab'. To change
the default, set the variable to the appropriate value:
maple to use the Maple Toolbox;
or
matlab to use The MathWorks (Extended) Symbolic Math Toolbox.
Note: By launching MATLAB with the commands provided in the "bin" directory
of the MATLAB installation, it is possible to use either toolbox without
changing MATLAB_SYMBOLIC. These commands are:
on Windows,
matlab-sym-maple.bat
matlab-sym-matlab.bat
on Linux and UNIX,
matlab-sym-maple
matlab-sym-matlab
NOTE: These commands are not available on Macintosh OS X
platforms.
Background: The Mathworks (Extended) Symbolic Math Toolbox may use old
versions of Maple libraries that conflict with those versions used by the
Maple Toolbox.
To resolve this conflict, the old binaries have been moved from
their original location. The MATLAB_SYMBOLIC environment variable
indicates to the MATLAB startup scripts which versions of the Maple
libraries should be visible to the MATLAB application.
