# FindDuration

## PURPOSE

FINDDURATION

## SYNOPSIS

function out = FindDuration(indx);

## DESCRIPTION

    FINDDURATION
       Usage: out = FindDuration(indx)

     This is a short little function that finds a jump in the indx vector
     and then spits out the number of elements before that jump.  It does
     this for all jumps it finds.  By a jump, I mean a discontinutity in the
     index.  For example, if the index vector is [1 2 3 4 5 8 9 10], there is
     a jump between 5 and 8.
