Macro: tri
Description: tri computes the triweight kernel, multivariate

Usage: y = tri(x)
Input:
x n x p matrix
Output:
y n x 1 matrix

Example:
library("kernel") 
x = aseq(-1, 21, 0.1) 
y = tri(x) 
t=createdisplay(1,1)                                      
show(t,1,1,x~y)                                    
Result:
The kernel is pictured
