A matrix
with the first column containing the partial derivative
with respect to omega.
Taking the derivative with respect to omega yields:
d/domega nu[j]^2 (omega) = (tau[j]^2 * omega)/8
Note: We are taking the derivative with respect to omega and not omega^2 as the omega relates to the slope of the process and not the processes variance like RW and WN. As a result, a second derivative exists and is not zero.
