Dear Friend,
I generated a series of N by 1 cells with different lengths. I want to generate a new vector, each element of this vector is the last value of the cells.i.e the first value of this vector is the last value of the first cell, the second value of this vector is the last value of the second cell, and so on. anyone can advise me how to achieve this?

What type/class of variable is in the cells? Characters? double arrays? Structures? Scalar integers?
Have you checked out cellfun()?

Hi, Walter,
would you please give more information. my problem, I want to find zscores for 100 time series data points. but the difference is I divide this time series into two parts, for instance, the first 50 as a group, I calculate the zscore for this 50 data points. then,I calculate the zscore for 51 data points, length 51, then take the last zscore of first 51 data points, add this zscore to the first 50 zscores, so the original zscore series length becomes 51, then, continue this process. here is the code, would you please have a look
n=length(data(:,2));
rolling=50;
rollingSuprise=zeros(n,1);
rollingSuprise(1:rolling)=zscore(data(1:rolling,2));
temp=cell(n-rolling,1);
for i=1:n-rolling
temp{i}=zscore(data(1:rolling+i,2));
end

NewVector = cellfun(@(v) v(end), YourCellArray)
