for my simulation I have to calculate several gradients and jacobian matrices. The equations are quite complex and with my current setup hard to read.
Here is some exampel code:
SetCoordinates(cartesian[x, y, z]);
alias(u = u(t, x, y, z), v = v(t, x, y, z), w = w(t, x, y, z)); alias(eta = eta(t, x, y, z));
U := VectorField(`<,>`(u, v, w));
The Divergence operator gives me a very compact result:
But Jaobian and Diff look like:
To achive a better readability I want to do two things (if possible):
1) hide the independet variables (t,x,y,z) in the result of Jacobian, Diff
2) display the result of Diff in a row vector (3x1) instead
Is this possible?
Thanks in advance for your help
