At present, I could be able to take grad of Ax, Ay and Az using calculate gradients module and finding curl operation in matlab externally.

Respected sir,

I am trying to model magnetic field from magnetic dipole. First step of curl (mag. moment m and r)/(r^3) is done by using sim forward mag field module. I am considering the output as magnetic vector potentials. To get the mag field of dipole, I am planning to feed the result to another sim for mag field module. I am searching for a module that can give del operators from which cross can be done with mag vec potentials (del x A(r)) to get B(r). 

where A(r) =(1/4pi)  (m x r )/r^3

m=(mx, my, mz),  r=(x, y, z), r = sqrt(x^2+y^2+z^2)

mx=I(t) *pi *a^2 *ax_cap

I(t) =current, a= radius of coil

​For simplicity, not considering the grad of electric field and conductivity is homogeneous. 

If I make a small circular coil node data as input and with the help of tutorial given in tms coil stimulation, is it possible to model a mag field from a coil  (magnetic dipole).  ​
Could you please help me with this.
