scicos_model - Scicos block functionality data structure

Description

Scicos block model data structure contains all information relative to the simulation functionalities of the block. Fields may be fixed by block definition or set.

If block is a super block, the fields state,dstate,ipar,blocktype,firing, dep_ut, are unused.

The rpar field contains a data structure similar to the scicos_diagram data structure.

DEFINITION

model=mlist(['model','sim','in','out','evtin','evtout','state',..
 'dstate','rpar','ipar','blocktype','firing','dep_ut',..
 'label'],sim,in,out,evtin,evtout,state,dstate,rpar,..
 ipar,blocktype,firing,dep_ut,label)

   

• model: Scilab mlist, Scicos model data structure defined by the formal name 'model' and containing the following fields:

FIELDS

• sim : list(fun,typ) or fun. In the latest case typ is supposed to be 0.
• fun : character string, the name of the block simulation function (a linked C or Fortran procedure or a Scilab function).
• typ : integer, calling sequence type of simulation function (see documentation for more precision).
• in : column vector of integers, input port sizes indexed from top to bottom of the block. If no input port exist in==[].
• out : column vector of integers, output port sizes indexed from top to bottom of the block. If no output port exist in==[].
• evtin : column vector of ones, the size of evtin gives the number of event input ports. If no event input port exists evtin must be equal to [].
• evtout : column vector of ones, the size of evtout gives the number of event output ports. If no event output port exists evtout must be equal to [].
• state : column vector, the initial continuous state of the block. Must be [] if no continuous state.
• dstate : column vector, the initial discrete state of the block. Must be [] if no discrete state.
• rpar : column vector, the vector of floating point block parameters. Must be [] if no floating point parameters.
• ipar : column vector, the vector of integer block parameters. Must be [] if no integer parameters.
• blocktype : a character with possible values:
• : 'c' block output depend continuously of the time.
• : 'd' block output changes only on input events.
• : 'z' zero crossing block
• : 'l' logical block
• firing : a vector whose size is equal to the size of evtout> It contains output initial event dates (Events generated before any input event arises). Negative values stands for no initial event on the corresponding port.
• dep_ut : 1x 2 vector of boolean [dep_u, dep_t], dep_u must be true if output depends continuously of the input, dep_t must be true if output depends continuously of the time.
• label : a character string, used as a label
