Hi!, I have this: m ={{a, b, c}, {d, e, f}, {g, h, i}}
which are the methods to create a list with one element of each groups of m.
For exemple m1 = {a,e,i}, the first, the second and the third element?
I've try with m1 = {#[[1]]} & /@ m; but the selection is only the first element for each group!!
thanks
