Jacobian Computation - Mathcad 11

Hello,

What is the syntax to determine the Jacobian of a matrix in Mathcad 11?

(Mathcad 11 File)

Thanks.

The Jacob() function that Werner shows is not implemented in Mathcad 11. It may have been added in Mathcad 14 or 15.

However former Mathcad Expert Tom Gutman implemented a function that produces the Jacobian, here's an example:

A Mathcad 11 file with all function required to run the Jacobian is attached.

Success!

From Mathcads help:

So here's the workaround using your function:

But I don't mean in Mathcad 15, but in Mathcad 11.
In Mathcad 15 I know it works.

Mathcad 15:

Mathcad 11:

Should it have the same result in Mathcad 11 as in Mathcad 15 with the same syntax?
Or is it done differently in Mathcad 11?

Aha.
Good.
It looks like the implementation you attached to Mathcad 11 for finding the Jacobian works.
Thank you.

Thanks.
