http://web.cvxr.com/cvx/doc/advanced.html Web1 Answer. Let A be symmetric positive definite matrix hence ∃ a diagonal matrix D whose diagonal entries are nonzero and A = P D P − 1 so A − 1 = P D − 1 P − 1 and T r ( A − 1) = T r ( D − 1). Now D being diagonal matrix with non zero diagonal entries D − 1 has diagonal entries reciprocal of the diagonal entries of D so T r ( D ... nisbets essentials auto fill water boiler
