How to return elements of 'A' using indices of 'B' ?

Hi all,

I have two signals 'A" and 'B' (attached) collected at the same time (same number of frames). I have identified 8 indices (frame numbers) in ''a'' (attached "a_indices'). Now I want:

• Return and save elements of 'b' between "a' indices 1-2, 2-3, 3-4, 4-5, 5-6, 6-7, 7-8

Can you help please?

a = thigh_orient_y ;
b = shank_orient_y ; 
idx = main_peak_location ; 

n = length(idx)-1 ; 
iwant = cell(n,1) ; 

for i = 1:n
    iwant{i} = b(idx(i):idx(i+1)) ;
end
