Gradient of the Scaling function (marginal in dimension k) of Xiong et al. with respect to eta

1	scalingGrad(X, knots, k)

`X`	an n*d matrix standing for a design of n experiments in d-dimensional space.
`knots`	a list of knots parametrizing the transformation.
`k`	dimension of the input variables for which the gradient is calculated.
