How can i implement this in matlab

r=5; re=3; ci={xi,yi,r}

Where xi, yi are random values of on grid

P is a point on grid (x,y)

d(ci,p)=sqrt((xi-x)^2+(yi-y)^2);

Then

Pcov(x,y,ci)= 1 if d(ci,p)<r-re

else exp(-0.5*(d(ci,p)-(r-re))^0.5) if r-re<d(ci,p)

else 0

The answer is...

(Written in invisible ink, just like the equation you did not post.)
