Group Numbers by cumsum (distance based)

Hi,

I have a distance vector that a vehicle travels at each second. (1Hz Data)

I want to create a new matrix that is including group names of each 150 meters The matrix is attached.

Every group will be ~150 meter (149m-152m what ever)

[ 1 1 1 1 1 1 ... 2 2 2 2 2 2 . ... 3 3 3 3 3 .... 4 4 4 4...... ]
