chandle

• DiagNewmark
• ExpNewmark
• nl_inout

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.

• chandle.numType lists currently implemented chandle subtypes.

DiagNewmark

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

ExpNewmark is an implementation of the Newmark scheme when assuming a fixed diagonal mass matrix for large explicit dynamic problems.

nl_inout

Support for observation performed in C. .iopt for standard integer options.

.N field : Nunl, (c,1),(c,2),cTrans, (b,2),(b,1),bTrans, Nopt[8],Niopt[9],size(unl,3)[10] .opt field ? tc[1] dt0[2] K[3] Fmax[4] Fu functions currently implemented in C are listed under nl_inout fun
