Inversion of jacobian matrices in metal—ligand—pH studies

Talanta, 1989
Many non-linear regression programs which optimize the stability constants of chemical equilibria make use of Jacobian matrices for both the simulation of speciation by Newton-Raphson iteration and the optimization of parameters by Gauss-Newton iteration.

Estimation of Sparse Jacobian Matrices and Graph Coloring Blems

SIAM Journal on Numerical Analysis, 1983
Given a mapping with a sparse Jacobian matrix, the problem of minimizing the number of function evaluations needed to estimate the Jacobian matrix by differences is investigated. This problem can be attacked as a graph coloring problem and this approach leads to very efficient algorithms.

Jacobian Matrices and Lyapunov Exponents

2017
The Lyapunov exponent λ represents a measure of stable or unstable change in the nonlinear behavior of systems. This exponent can be calculated as the real components of the eigenvalue solutions to the differential equations describing a system. They can be linked to transition points between single period and period doubling events in bifurcation ...

Compensation of Robot joint variables using special Jacobian matrices

Journal of Robotic Systems, 1991
AbstractIn dealing with an industrial manipulator, the end‐effector accuracy is a major concern. The positioning of the end effector is determined by the controller that utilizes the data from a closed‐form kinematic inversion. The closed‐form inversion uses nominal, i.e., manufacturer specified, values of link lengths, twists, and offsets.

Computational aspects of jacobian matrices

1997
The underlying theme of this talk is the jacobian matrix of a (finite) set of multivariate polynomials f = {l1…-, lm} ⊂ R = k[X] = k[X1…,Xd]. Here k stands for a field, eventually of characteristic zero. Jacobian matrices are classical, useful in almost all branches of mathematics and there is a famous conjecture that bears the name!
