How can I select only the values in a Matrix, which don't have the value?

I search for an expression for that, because I can't divide by 0 and for later use I need Matrixelements which don't have the value 0. Would be glad, if someone could help me.

   Matrix1Quotient = MatrixB ./ MatrixA;

This says that the matrixelements must not be 0. But don't select the elements which are ~=0:

Mat1Quot(:,:)~=0

i=find(~MatrixA);
Matrix1Quotient = MatrixB(i)./MatrixA(i);

Thanks! That's the expression I was searching for! :-)

Ah, as a result I get a skalar. Unfortunately I need a Matrix. Does there any find-expression exist, which gives out a matrix?
