BUMPV
A bump function s.t. v(x-1)^2+v(x)^2+v(x+1)^2=1 for abs(x)<1
Contents
Description
y = bumpV(a,b,N) a, b are integers; N is smooth order rescale x =[a:b] to t = 2/(b-a)*(x-a)-1 in [-1,1] return V(t) s.t. V(t-1)^2+V(t)^2+V(t+1)^2 =1 for abs(t)<=1;
Examples
a = -10; b = 10; y = bumpV(a,b); plot(a:b,y);
