how to find distance between consecutive points

Hi!

I have a matrix

A=[51.7365160000000 10.7978860000000;51.7366230000000 10.8319610000000;51.7389880000000 10.7849260000000;51.7424430000000 10.9195510000000;51.7443820000000 10.9157750000000;51.7448080000000 10.9160750000000;51.7523270000000 10.8756060000000;51.7525920000000 10.8758210000000;51.7526190000000 10.8738470000000;51.7526460000000 10.8763360000000;51.7528580000000 10.8477970000000;51.7530180000000 10.8776230000000];

The first column of A indicate latitude, the second column indicate longitude of differente points. I want to find the distance between consecutive points. I have used the function pdist in this way

a = pdist(A,'euclidean')';

but it gives the distance between all points and not only between consecutive point.

Can you help me to solve the problem?

thanks

sqrt( sum( abs( diff( A ) ).^2, 2 ) )

There may be a builtin function that does it to, but something so simple I tend to just do myself if I'm not aware of a builtin function off-hand.
