Detailed Description

Helper that builds the p-th symmetric power of a 1-by-n matrix.

Note

AI-generated documentation. Verify against the source before relying on it.

Invoked through the static symmetricPower(m, p) entry point, which validates that the input has exactly one row and then runs the recursive multi-index walker. Each resulting column corresponds to a multiset of p columns of m whose entries are multiplied together — the standard symmetric-power-of-a- matrix construction. Used to implement the engine-side symmetricPower matrix operation.
