E (Electric field ) = [Summation(from k=1 to N) rho subcript k * delta * R(vector) ]/[4*pi*e*R^3]

where R( vector) = r- r subscript k

R=(x-x subcript k )ax + (y-y susbcript k)ay +(z-z subscript k)az

Please provide me a solution for the program and also how to plot the graph clearly shwing the variation ???

rho -- magnetic susceptibility would be my guess

e -- fundamental electric charge?

xk, yk, zk -- I speculate that these are the positions of wire segments, possibly of length delta. But orientation would matter...

@Walter: I rather suspect this is simply Coulomb's law in the so-called "absolute practical units" with a set of electrostatic charges, rho_k, at positions (x_k,y_k,z_k) and unit vectors pointed from each charge to a given field position at r = (x,y,z). I was hoping to entice Asutosh into giving us the description, however, to show an understanding of what was being computed. Having to think out such a description might make it easier to come up with an understanding of the necessary matlab code for computing it.
