Function: | contour3 | |
Description: | contour3 computes lines and points for a contourplot of a four dimensional dataset at level c |
Usage: | {lt, pt} = contour3 (x, c) | |
Input: | ||
x | n x 4 matrix | |
c | scalar | |
Output: | ||
lt | m1 x 2 line matrix | |
pt | m2 x 3 point matrix |
x = grid(-#(3,3,3), #(0.5,0.5,0.5), #(13,13,13)) f = exp(-0.5.*sum(x^2,2))./(2.*pi)^1.5 z = sort(x~f, #(1,2,3,4)) {lt,pt} = contour3(z, max(f)./2) d = createdisplay(1,1) show (d,1,1,pt)
You will see a ball corresponding to a contourball.
