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];

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

I did something like this:
newS2 = arrayfun(@(y) structfun(@(x) x(3:end-2),y,'uni',false),S)
Or:
for i = 1:numel(S)
newS(i) = structfun(@(x) x(3:end-2),S(i),'UniformOutput',false)
end
