Subroutine Type

Utility/Data Access

Definition

Obtains various system states, for example, Displacement and Velocity, and makes them available to user-defined subroutines.  SYSARY should be called with the appropriate input arguments (listed below) and it returns the corresponding system state.

Calling Syntax

Fortran

CALL SYSARY (FNCNAM, IPAR, NSIZE, STATES, NSTATES, ERRFLG)

 

C

c_sysary (fncnam, ipar, nsize, states, nstates, errflg)

 

Python

[states, errflg] = py_sysary (fncnam, ipar)

 

MATLAB

[states, errflg] = m_sysary (fncnam, ipar)

Attributes

FNCNAM

A variable that specifies the name of the function for the SYSARY call.  Valid function names are listed below.

 

IPAR

A vector containing input parameters for the FNCNAM.  The size of this array must be NSIZE.

 

NSIZE

A scalar integer variable that contains the number of parameter for the SYSARY call.

 

STATES

The values returned from the SYSARY call.  The dimension of the double precision array STATES depends on the function name used.

 

NSTATES

An integer value that represents the number of values stored in the STATES array.

 

ERRFLG

A logical flag that represents the success of the SYSARY function call.

•False/0 – Success.
•True/nonzero - Error in the function call

Complete Definition

The function can be called only by a subset of user defined subroutines, for example: ARYSUB, CONSUB, DIFSUB, GFOSUB, REQSUB, SENSUB, SEVSUB, SFOSUB, TUNSUB, VARSUB, VFOSUB, and VTOSUB.  In particular, it cannot be called by UCOSUB, COUSUB, COUXX, COUXX2, FIESUB, MOTSUB, GSESUB, GSEXX, GSEXU, GSEYX and GSEYU.  For the above mentioned routines, system states must be explicitly passed as input arguments and cannot be extracted via the SYSARAY or SYSFNC call.
