I have a matrix A with 3 columns and multiple rows,
A =
a_1 b_1 7
a_1 b_1 8
a_1 b_1 4
a_2 b_2 2
a_2 b_2 5
a_2 b_2 3
a_2 b_2 2
a_3 b_3 9
a_3 b_3 8
a_3 b_3 12
a_3 b_3 25
a_3 b_3 10
... ... ...
I would like to make another matrix B that contains the first two rows of each couple of parameter (a_i, b_i) in A , such that
B =
a_1 b_1 7
a_1 b_1 8
a_2 b_2 2
a_2 b_2 5
a_3 b_3 9
a_3 b_3 8
... ... ...
Note that the value a_i and b_i ae not unique, but each couple (a_i, b_i) would be different from (a_j, b_j).
Thanks in advance!
