Updating new value in a loop

I have original x-cell and y_cell

for big_loop=1:100

    for...
       for...
    if
    。。。。。。。
    after a series of operation
    I have a new x_cell and y_cell

end

now I need to put x_cell and y_cell again in the loop, I thought it will update automatically, but some of them have been updated but some are not,dimension error, why there is a dimension error, for every time, x_cell and y_cell should be a new value.

I tried to remove the big loop, and it works with no problem, but only do it one, I need to do that for several times, until certain criterion is reached.

how should I do that?

Hi,

    You can do it by padding the data of x_cell and y_cell values by zeros or ones(If you know precise data length of x_cell and y_cell ) initially.

e.g. x_cell=zeros(size(x_cell))
