Designers getting ready to choose a linear actuator for a specific device or machine should have a list of questions ready to ask suppliers and manufacturers of those devices. These lists usually ...

Methods for solving symmetric indefinite systems are surveyed including a new one which is stable and almost as fast as the Cholesky method. Journal Information SIAM Journal on Numerical Analysis ...

We consider the solution of ill-conditioned linear systems using the singular value decomposition, and show how this can improve the accuracy of the computed solution for certain kinds of right-hand ...
