For $p \in [1, \infty)$, the $p$-Schatten norm of a matrix $A$ is defined as $\|A\|_p = Tr(\left|A\right|^p)^{\frac{1}{p}}$, where $\left|A\right| = (A^* A)^{\frac{1}{2}}$. Is there any function to calculate those norms?

Total[SingularValueList[A]^p]^(1/p)
or
Power[Tr[MatrixPower[A\[Transpose] . A, p/2]], 1/p]

$\begingroup$ Why not use
Norm[...,p]
on theSingularValueList
? $\endgroup$– The VeeCommented Aug 1, 2022 at 8:31 -
