Hi

I have a 3×3 matrix, and i would like to find the rows where the 1st and 2nd columns equals a value.

M=[1 2 3

1 1 3

2 1 3]

Lets say I would like to find the row where both the 1st and 2nd column equals 1. In this case i would like to find row 2, and be able to extract the values of that row, i.e. 1 1 3.
