I have a structure containing multiple fields of size 1XN and 3XN. I'm looking for a simple way to extract partial data, e.g. the new structure will contain the same fields as the original, but of sizes 1XN-x and 3XN-x.
Thanks.

>> S.A = 0:3;
>> S.B = 4:9
S =
scalar structure containing the fields:
A =
0 1 2 3
B =
4 5 6 7 8 9
>> x = 2;
>> Z = structfun(@(v)v(:,1:end-x),S,'UniformOutput',false)
Z =
scalar structure containing the fields:
A =
0 1
B =
4 5 6 7

Thanks. Is it possible to do the same using a logical array, instead of 1:end-x?
