getenv() returns the results that are not complete.

On the windows system the environment variable CLASSPATH is:

.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;D:\QMDownload\6;

When I open cmd and type "set CLASSPATH" it echos:.

CLASSPATH=.;C:\Program Files\Java\jdk1.7.0_80\lib\dt.jar;C:\Program Files\Java\j
dk1.7.0_80\lib\tools.jar;D:\QMDownload\6

However,() when I type

!set CLASSPATH 

in matlab command windows,I get:

.;C:\Program Files\Java\jdk1.7.0_80\lib\dt.jar;C:\Program Files\Java\jdk1.7.0_80\lib\tools.jar;

When I run

getenv('CLASSPATH')

ans =

.;C:\Program Files\Java\jdk1.7.0_80\lib\dt.jar;C:\Program Files\Java\jdk1.7.0_80\lib\tools.jar;

We can see that "D:\QMDownload\6;" was lost in matlab's results.

I'm wondering why the last part was trimed in matlab, even when using system command !.

I'm sure that I have restared matlab for several times after updating the CLASSPATH just to refresh matlab's system enviroment.

The missing part come back after I restart the PC two days later.
