makeunique(in, scale)

Function that accepts a vector with duplicate values and adjusts the duplicates

This routine takes a vector of observations that contains duplicated values and returns a vector in which the duplicates have been adjusted by a specified fraction of the standard deviation of the vector, returning a vector with the same mean. It also returns the cumulative probability for the range. The intended purpose is to be able to determine the cumulative probability of a new observation using interp1:
a=[1:10,7,7,7];
probability = interp1(makeunique(a),5);
