clear all
[x, y, z] = meshgrid(-50:1:50,-50:1:50,-50:1:50);
i = 1/(x.^2+y.^2+z.^2).^(3/2);
j = 1/(x.^2+y.^2+z.^2).^(3/2);
k = 1/(x.^2+y.^2+z.^2).^(3/2);
quiver3(x,y,z,i,j,k)
Could anyone tell me where is the issue, nothing show up in the figure but no error founded.

i(~isfinite(i)) = nan;

k(~isfinite(k)) = nan;
