how to load the data from strut

I want to load the data which can be accessed by

VarName = Cell1.cyc++++.v()

where ++++ indicates the number like

0000, 0100, 0200, 0300,......1000,1100, ....8000, 8100, 8200.

I want to create a matrix from it, where it will contain the only 1st and last element of v() for all cyc++++ (0000 to 8200)

so how can I do it without loading each file one by one?

please help.....Thanking in advance.

Are these in different files, or already in one struct ?

struct Cell1 contains cyc++++ (0000 to 8200), then each cyc++++ contains Ch1, Cd1, Q1 as struct and then each Ch1 contains v (3371 by 1) matrix, t (3371 by 1) matrix, I (3371 by 1) matrix

so it is Cell 1---> cyc++++--->Ch1--->v()

sorry .... it is

VarName = Cell1.cyc++++.Ch1.v()

The best solution is to redesign your data so that you are not forcing meta-data into fieldnames.

Forcing meta-data into fieldnames is one way that beginners force themselves into writing slow, complex, obfuscated, buggy code (exactly as you are finding out now). Your code would be much simpler if you stored the meta-data in the variables rather than in the fieldnames.

In the case where it is already loaded into Cell1 then

output_matrix = [structfun(@(S) S.V(1), Cell1(:)), structfun(@(S) S.V(end), Cell1(:))];

Sorry ....there is some correction in question

it is

VarName = Cell1.cyc++++.Ch1.v()

[Walter Roberson]

output_matrix = [structfun(@(S) S.Ch1.v(1), Cell1(:)), structfun(@(S) S.Ch1.v(end), Cell1(:))];

provided that your Ch1 are scalar structures.
