I've got no problem when I compile the following two equivalent expressions using "perl *.pl" from the command line.

----------------------------------------------

$string= "[ -1 0 -2 ]\n[ 0 1 1 ]\n[ 1 0 1 ]\n"; $G=MatrixReal1->new_from_string($string);

--------------------------------------------

$G=MatrixReal1->new_from_string(<<"MATRIX"); [ -1 0 -2 ] [ 0 1 1 ] [ 1 0 1 ] MATRIX

-------------------------------------------

With second code, everything was O.K. But an error message came up when I tried to see on the webpage with first code and the error is :

-------------------------------------------------

Software error

Can't use an undefined value as an ARRAY reference at /usr/calculus/webwork/system/courseScripts/displayMacros.pl line 582. main::l2h_sticky_answers called at /usr/calculus/webwork/system/cgi/cgi-scripts/processProblem8.pl line 471 eval {...} called at /usr/calculus/webwork/system/cgi/cgi-scripts/processProblem8.pl line 78

------------------------------------------------

Any comment will be helpful. Thanks in advance.

cwyi.
