I have one value of "strain(:,:,1)" in 3*1 matrix. i need value of strain(:,:,2), strain(:,:​,3).......​strain(:,:​,N) means nth term.in each layer i need same value of strain. how can i copy value of strain for nth term.

strain(:,:,1)

ans =

    0.0000
    0.0017
   -0.0018

This would have been so much easier if you hadn't wanted the result to be per layer. What I would have suggested is using

T = arrayfun(@(pane) q(:,:,pane) * curvature, 1 : size(q,3), 'Uniform', 0);
curveatureqi = cell2mat( T );

Notice the lack of the reshape(), which was only needed to get the answer to be per layer. With this version, the result is going to be a 3 x 20 array which you can then easily index into.

No no...this is different case....i have to copy into mat and reshape. i have to solve very complex equation of nth layer that's why i need each value from each layer and multiply each layer. please tell me command for copy strain

If strain is a 3 x 1 x 20 matrix then strain(:,:,n) just like you have.

If strain is a 1 x 1 x 20 cell matrix, each element of which is a 3 x 1 matrix, then strain{1,1,n} or equivalently in that situation, strain{n}
