// Element-wise vector multiplication. Multiplies each element of vector `v1` by
// the corresponding element of vector `v2`. The vectors should have the same dimension.
// Returns a vector of the products.
// Element-wise multiplication. Multiplies each element of `v1` by the corresponding element of `v2`.

// vmul([3,4,5], [8,7,6]); // Returns [24, 28, 30]
