In this paper, a new method for solving nonlinear simultaneous equations is proposed.This method employs an initial symmetric factorization of the Jacobian matrix, and then up-dates the upper triangular factors directly at each step. Iterations are generated using forwardand backward substitutions ...
The set of all points which a manipulator can reach without intrusion. Sometimes the shape of the work space, and the position of the manipulator itself can restrict the work envelope. Work Envelope (Space) The volume of space within which the robot can perform given tasks. ...
X = sort (Y) is used to sort the elements of Y in the ascending order. If input Y is a vector, the function sort (Y) will sort the elements of the vector Y. If input Y is a matrix, the function sort (Y) will treat the columns as vectors & will sort each column. X = sort...

Here it simply is not a proper variance matrix, and the Hausman test becomes undefined. suest m1 m2 estimates the simultaneous (co)variance of the coefficients of models m1 and m2. Al- though suest is technically a postestimation command, it acts like an estimation command in that it ...
