Easiest way to multiply vector values together?

Question

I\'ve got a silly question. I took a vector math class about 10 years ago and could\'ve sworn I remembered an operation that allowed me to multiply the values of a vector to

Answer 1

When we electrical engineers want to sound smart, we call it the Hadamard product, but otherwise it’s just the “element-wise product”.

What library are you using? GLSL? Eigen? GSL? We can look for how to do element-wise multiplication in it. (It can often be accelerated using SIMD, so an optimized implementation provided by a library will be faster than your hand-rolled function.)

Edit: Unity calls this Vector3.Scale: “Multiplies two vectors component-wise.”
