A matrix
with the first column containing the partial derivative with respect to theta
and the second column contains the partial derivative with respect to sigma^2
Taking the derivative with respect to theta yields:
d/dtheta v[j]^2 (theta, sigma2) = (sigma2*(2*(theta+1)*tau[j]-6))/(tau[j]^2)
Taking the derivative with respect to sigma^2 yields:
d/dsigma2 v[j]^2 (theta, sigma2) = ((theta+1)^2*tau[j]-6*theta)/(tau[j]^2)
