MATLAB: Delete end points from columns in a structure array

Question

Hello.

I have a structure array S (1 x 50000) with 10 fields. The elements in the fields are column matrices (1 X M) with their size consistent for given S(i).

I want to delete tails in all the 10 fields (2 data points on each side – at the beginning and the end of the vector) which, should result in the array size of (1 X M-4).

For example, the input is something like this

S(1).f1=[1,2,3,4,5,6,7,8,9,10];

S(1).f2=[2,4,6,8,10,12,14,16,18,20];

S(2).f1=[10,20,30,40,50,60,70];

S(2).f2=[150,200,250,300,350,400,450];

I want the output to be,

S(1).f1=[3,4,5,6,7,8];

S(1).f2=[6,8,10,12,14,16];

S(2).f1=[30,40,50];

S(2).f2=[250,300,350];

Answer 1

S = cell2struct(cellfun(@(x)x(3:end-2),struct2cell(S),'un',0),fieldnames(S));
