FindDuration

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.

0006 % This is a short little function that finds a jump in the indx vector
0007 % and then spits out the number of elements before that jump.  It does
0008 % this for all jumps it finds.  By a jump, I mean a discontinutity in the
0009 % index.  For example, if the index vector is [1 2 3 4 5 8 9 10], there is
0010 % a jump between 5 and 8.
