I have a table:
1 23
2 24
3 21
4 34
1 89
2 23.2
3 34.8
4 -23.1
and it continues with the first column always being in the sequence 1-2-3-4.
I need to subract the first element next to 1 from the second element next to 1, so: 89-23. Then all elemets represented by the number 2 in the 1st column, so: 23.2-24. etc.
The outcome should be the following vector: [66 -0.8 13.8 -57.1].

A=[1 23
2 24
3 21
4 34
1 89
2 23.2
3 34.8
4 -23.1];
My_Table= table(A(:,1),A(:,2))
B=table2array(My_Table(:,2));
ind1 = 1:4;
ind2 = ind1 + 4;
output=B(ind2)-B(ind1)
