Gradient Clip by Value Vector

Problem

Value clipping clamps each gradient coordinate into [-clip, clip] independently.

Given the gradient and the clip value, return the clipped gradient.

Hint

Apply the box projection coordinatewise.

case 1

in: [[5,-5,0],2]

expected: [2,-2,0]

case 2

in: [[0.5],1]

expected: [0.5]

case 3

in: [[-3,3],3]

expected: [-3,3]
