problem with Part function


Just a little problem:
I've a matrix of zeros, say:
mat=Table[Table[0,{5}],{5}];
then, I've a point in xy axys,
xy={3,3};
now, I want the position {3,3} of matrix becomes 1;
if I write
mat[[xy]]=1; or mat[[{3,3}]]=1; it doesn't work; only mat[[3,3]]=1 
works, but I don't want rewrite all.
I think I've to use something like Map, Thread, Apply or so, but I don't 
know what and how exactely;
please, someone help me.
THANK YOU
