Replace Element of an Array with another Array

Hello, I have an initiator matrix

In=[1 0 1;0 0 0;1 0 1];   % Initiator Matrix
and a zero matrix
zero=zeros(3);

1. Step 1I need to find all elements in "In" that are equal to 1 and insert "In" in that elements place, all elements with "0" insert the matrix "zero" in that place. This is a cellarray.
2. Step 2I need to convert to the cellarray to a matrix. I think I do that with cell2mat() command right?

Thanks for your help.
