here is my code

clear

format compact;

load 'levelset (1).mat'

% get the divergence field

[dFdx, dFdy, dFdz] = Func_gradient3D(X, Y, Z, F);

dFdx0=dFdx; dFdy0=dFdy; dFdz0=dFdz;

magDF = sqrt(dFdx.^2 + dFdy.^2 + dFdz.^2);

dFdx=dFdx./magDF;

dFdy=dFdy./magDF;

dFdz=dFdz./magDF;

kappa = func_divergence(X, Y, Z, dFdx, dFdy, dFdz);

[H, delta, mask] = func_HeavisideDelta(X, Y, Z, F, 2);

U = sqrt(Ux.^2 + Uy.^2 + Uz.^2);

[dUxdx, dUxdy, dUxdz] = func_gradient3D(X, Y, Z, Ux);

[dUydx, dUydy, dUydz] = func_gradient3D(X, Y, Z, Uy);

[dUzdx, dUzdy, dUzdz] = func_gradient3D(X, Y, Z, Uz);

Please supply executable code that reproduces the error.

Without the data, we can not run your code to reproduce the error and subsequently provide any suggestion/solution.

Also, we don't know what is the error you got, so, please copy and paste the whole error message i.e. all of the red text.
