Replace value from cell from particular index

I got two 3 x 3 sub-matrix from mat2cell

cell1=[1 1 1; 1 1 1; 1 1 1];
cell2=[0 0 0; 0 0 0; 0 0 0];

i want to replace value from cell1 index (2,2) with cell2 index(2,2)

cellresult=[1 1 1; 1 0 1; 1 1 1];

Thanks

cell1=[1 1 1; 1 1 1; 1 1 1];
cell2=[0 0 0; 0 0 0; 0 0 0];
ii1=[2 2]
ii2=[2 2]
cell1(ii1(1),ii1(2))=cell2(ii1(1),ii1(2))

Thanks for the answer , but how to save the

cell1(ii1(1),ii1(2))=cell2(ii1(1),ii1(2))

into new variable like cellresult or cell3

I want to loop the cellresult into sub matrix and then using cell2mat to create new matrix

[Stef]

 cell1{i+1,j+1}(2,2)=cell2{i+1,j+1}(2,2)

works for me , Thanks for the answer
