Help Text

FINDCLOSEST - Find entries of closest elements between two vectors 
 function VecInd  = findclosest(VecGuess, VecRef);
 Find entries of closest elements between two vectors 
 VecGuess is a vector for which one wants to find the closest entries in vector VecRef
 VecInd is the vector of indices pointing atr the entries in vector VecRef that are the closest to VecWin
 VecInd is of the length of VecGuess
 
 In other words, VecRef(VecInd(i)) is the element of VecRef closest to VecGuess(j)
 
 VecRef and VecGuess do not need to be the same length
