Hello,

How can I get "yy+uu" instead of "[yy+uu]" in my example below? I need
to remove brackets. They become problematic when going to more complex
calculations.


(%i185) func(a,b) := a[1]+b[1];

(%o185) func(a,b):=a[1]+b[1]

(%i188) a:matrix([yy], [zz]);
        b:matrix([uu], [ww]);

(%o188) matrix([yy],[zz])
(%o189) matrix([uu],[ww])

(%i190) func(a,b);

(%o190) [yy+uu]


Thank you,
Iai
