MATLAB: Replace value from cell from particular index

Question

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

Answer 1

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))
