Zhongzhi Zhang · Mathematica Applicata · 2007
Let X,B be a displacement matrix and load matrix respectively by test data.Assume C (obtained by using the finite-element method) to be an estimate matrix of the analytical model.Find the generalized centro-symmetric matrix to minimize the Frobenius norm of C-A and X=B.The perturbation of the solution is analyzed.Numerical results show that the method is feasible and effective.
