The JACOBIAN statement defines the JACOBIAN matrix J for a system of objective functions. For more information, see the section "Derivatives". proc nlp tech=levmar; array j[2,2] j1-j4; lsq f1 f2; ...
The figure below illustrates the core workflow of the APSMC framework proposed in the paper. This framework reformulates nonlinear structural dynamics into a time-varying state-space model via local ...
Abstract: Accurate specification and rigorous analysis of Jacobian matrix are indispensable to guarantee correct evaluation on the manipulator kinematics performance. In this paper, a formal analysis ...
In this paper we prove global univalence results in $R^{4}$ when the Jacobian matrices are of the Leontief type. Proofs of these make use of ideas from Gale-Nikaido ...
The NLP procedure provides a variety of ways for estimating parameters in nonlinear statistical models and for obtaining approximate standard errors and covariance matrices for the estimators. These ...
