Hello,
I would greatly appreciate any/all help with this issue:
I have a 18 x 1 cell array. Each cell in this array contains an (1024 x 1024 x 50 , value = double) matrix. Thus, there are a total of 18 of these matrices, each one stored in a separate cell.
I would like to modify each of the matrices by cutting out the last 2 "frames" --> producing a total of 18 (1024 x 1024 x 48) matrices, each one stored in a separate cell.
Please help! Thanks :)

result = cellfun(@(x)x(:,:,1:end-2),your_cell_array,'uni',false);

@(x)x(:,:,1:end-2) creates an anonymous function on the fly. It takes an input x and returns a truncated version of x with the last two pages removed. E.g.,
>> y = reshape(1:24,2,3,4)
y(:,:,1) =
1 3 5
2 4 6
y(:,:,2) =
7 9 11
8 10 12
y(:,:,3) =
13 15 17
14 16 18
y(:,:,4) =
19 21 23
20 22 24
>> f = @(x)x(:,:,1:end-2)
f =
@(x)x(:,:,1:end-2)
>> f(y)
ans(:,:,1) =
1 3 5
2 4 6
ans(:,:,2) =
7 9 11
8 10 12
