NCAlgebra version 6.0.2 fails to compute the gradient of the trace of a quadratic product. Works fine in version 5.0.6final. Am I missing something?

NCGrad[tr[x**tp[x]], x]

NCPolynomial::NotPolynomial: Expression is not an nc polynomial.
NCGrad::Failed: Do not know how to calculate NCGrad. Expression tr[x ** tp[x]] is most likely not rational or invalid.

  • $\begingroup$ My pleasure. There was a minor glitch in the packaging so you might want to download the latest v6.0.3 version just to be sure you get the full functionality. $\endgroup$ Nov 4, 2023 at 22:28
