I have a two-column matrix M that contains the start/end indices of a bunch of intervals:
startInd EndInd
1 3
6 10
12 12
15 16
How can I generate a vector of all the interval indices:
v = [1 2 3 6 7 8 9 10 12 15 16];
I'm doing the above using loops, but I'm wondering if there's a more elegant vectorized solution?
v = [];
for i=1:size(M,1)
v = [v M(i,1):M(i,2)];
end
