We can exploit the symmetry of a real, positive definite, symmetric matrix by using the Cholesky decomposition to compute the inverse.The built-in MATLAB inv function uses LU decomposition which requires extra pivots and operations. Rarely does one actually need to compute the inverse of a matrix...

% Original model: y = X*beta + u% We are concerned that a regressor in X% could be endogenous.% W contains the instruments and all regressors in X% except the suspected one.% An example:% m_t = b1 + b2*r_t + b3*y_t + b4*m_(t-1) + b5*m_(t-2) + u_t% In this model, we have a concern that r_t could...
