First Element Greater Than

I have a 720 x 1 vector that I would like to modify to include all entries up to and including the first element greater than 100. So if the vector is

[0, 4, 8, 19, 101, 120]

the modified vector would be

[0, 4, 8, 19, 101].

How I would accomplish this? Thanks!

a = [0, 4, 8, 19, 101, 120];

b = a( 1:find( a > 100, 1 ) );

This assumes the data is sorted which your example seems to imply.
