Compares the projection in pData with the original data in Data and calculates the rank-based smoothed recall and precision.
klrank(Data, pData, NeighborhoodSize)Matrix of original data
Matrix of projected data
Sets the 'effective number of neighbors' used to control the width of the Gaussian
Rank-based smoothed recall and smoothed precision. It's important to note that all values are the real result substracted from one. So precision_best is (1-precision_best).
