     "As part of the `hypercube` package, the `CubeMath` library is designed to offer many of `numpy`'s math operations for Hypercubes. As part of this effort, we have also developed `VectorizedCubeMath`, an experimental library, that offers SIMD-accelerated operations through [the Vector API](https://openjdk.org/jeps/426). It's worth making note here that [the Vector API](https://openjdk.org/jeps/426), as of 08/18/2023, is an incubator module in Java, and so it should be regarded as highly experimental.\n",
