merge values in matrix

hey guys,

I have a matrix :

Coordinates =

                    62.875 10 63.617 31
                     75.45 55 66.725 61
                     65.23 32 11.444 76
                    68.077 63 74.936 134

I'd like to merge them as:

Merged =
                    62.875 10 66.725 61
                    65.23 32 74.936 134

That is, merge every 2 rows as follows: the first 2 values in the 1st row and the last 2
                                                        values in the 2nd row.

Some help would be appreciated?

Ian

 M = [C(1:2:2*floor(end/2),1:2),C(2:2:2*floor(end/2),end-1:end)];

where C is the Coordinates array and M is Merged.
