如何在Scala Breeze中压缩两个DenseVectors? [英] How to zip two DenseVectors in Scala Breeze?

问题描述

我想压缩两个DenseVectors并在每对上执行一个操作，并获得一个新的向量作为结果.使用scala-breeze实现此目标的最佳方法是什么?

I'd like to zip two DenseVectors and perform an operation on each pair, and obtain a new vector as result. What is the best way to achieve this using scala-breeze?

我可以使用它们的data字段来解决它，但是我需要根据结果数组构造一个新的DenseVector.

I can work around it by using their data field, but I'd need to construct a new DenseVector from the resulting array.

推荐答案

我应该只对DenseVector做一个方法，但是

I should probably just make a method on DenseVector, but

breeze.linalg.zipValues(dv1, dv2){(v1, v2) => ??? }

应该这样做.
