Nearest interpolation

Find the nearest neighbor for a set of data points

nn(p, y, q)

Arguments

p	matrix of variable values, each row is a data point
y	vector of values, each entry corresponds to one row in p
q	vector of variable values, each entry corresponds to one column of p

Value

an interpolated value for q

Details

nn finds the n-dimensional nearest neighbor for given datapoint
