how to index a cell array

Hi, I encountered a Matlab problem again. I want to access all struct field elements, which is an element of a cell array, at one time, not using loop. Such as:

s{1} = struct('ID',1,'other field',...);
s{2} = struct('ID',2,'other field',...);

I want to access all ID values in the cell s, I write the code like this:

IDs = [s{:}.ID];

This does not work, how to access all ID values not using for loop, please?

If you used just one non-scalar structure (rather than lots of scalar structure in a cell array) then the solution would be very simple:

S(1) = struct('ID',1,'other field',...);
S(2) = struct('ID',2,'other field',...);
[S.ID]

Simpler, more efficient code through better data design. Why make your code more complex than this?

Thank for you answer.

I'm doing information fusion with matlab, the track numbers vary dynamic, a cell struct is convenient to store track information.

You can do this in Two steps

temp = [s{:}];
allIDValues = [temp.ID];

[Stephen23]

Note that in Ameer Hamza's answer the first line of code converts your cell array of scalar structures into one non-scalar structure. If you had stored your data in a non-scalar structure in the first place, then you would not need this extra step.

thank you for your answer. I will try it
