function indices=where(conditional)
%    where(condition)
%       
%      Returns the array indices corresponding to the array locations where
%      a specified condition is true.  This function only works on vectors,
%      not arrays
%
%      For example:
%
%         ndex=(where(bob>0.02))
%
%      Will be all values of bob that are greater than 0.02
