I have installed Matlab 7R14 for linux  ,but when I load it,an error 
occured:

expr:illegal option --r
usage:expr [-e] expression
/compat/linux/usr/local/matlab/bin/matlab: line 386: [: -ne: unary 
operator expected
/compat/linux/usr/local/matlab/bin/matlab: line 1:/lib/libc.so.6: cannot 
execute binary file
Opening log file: /home/hxsong/java.log.38374.........
 

Now the matlab logo cannot continue .
