Purpose
chandle objects are used to streamline communication between mex and MATLAB in iterative processes.
Creation generates a C copy of the matlab array and returns a vhandle.chandle object containing the ID. Register the chandle object for mexAtExit.
DiagNewmark is an implementation of the Newmark scheme when assuming a fixed diagonal full Jacobian as occurs in modal domain transients (explict or implicit).
ExpNewmark is an implementation of the Newmark scheme when assuming a fixed diagonal mass matrix for large explicit dynamic problems.
Support for observation performed in C. .iopt for standard integer options.
