I have a data structure which is 4 dimensional having dimensions of (9,1000,40,6). I have converted it to the following picture
Each of this 6 cells now has 1x40 data which looks as follows,
It goes from 1 to 40 each having 9X1000 size array. How can I convert this data to 40x9x1000?

Why not just convert it to the correct shape in the first place?:
A = your 9x1000x40x6 array
C = squeeze(num2cell(permute(A,[3,1,2,4]),1:3))

Hey I have a similar issue. I have a 4-D double (a 188x194x1x182 matirx, which is x,y,depth,time) the depth is 0 for all of them and I need to convert it to a 188x194x182 matrix. How can I do this in a similar way?

@Alex: where A is your array:
A = permute(A,[1,2,4,3])
