generic_block3
Generic block
Block Screenshot
Description
The block provides a generic interfacing function but the computational function needs to be defined separately, either as a Scilab function or a Fortran or a C function. Besides the name of the function, user should specify information such as the type, whether or not the block contains a direct feed-through term. The function realising computational functions of generic blocks of a Scicos diagram must be saved along with the diagram and loaded or dynamically linked before simulation.
Parameters
Simulation function
Name of the function to be loaded.
Properties : Type 'str' of size 1
Function type
Type of the computational function supported by Scicos.
Properties : Type 'vec' of size 1
Input ports sizes
Number of regular input ports.
Properties : Type 'mat' of size [-1,2]
Input ports type
Set the datatype of the regular input ports.
Properties : Type 'vec' of size -1
Output port sizes
Number of regular output ports.
Properties : Type 'mat' of size [-1,2]
Output ports type
Set the datatype of the regular output ports.
Properties : Type 'vec' of size -1
Input event ports sizes
a vector of ones, size of event input ports. The size of the vector gives the number of event input ports.
Properties : Type 'vec' of size -1
Output events ports sizes
a vector of ones, size of event output ports. The size of the vector gives the number of of event output ports.
Properties : Type 'vec' of size -1
Initial continuous state
A column vector of Initial State Conditions.
Properties : Type 'vec' of size -1
Initial discrete state
A column vector Initial discrete Conditions.
Properties : Type 'vec' of size -1
Initial object state
A Scilab list that defined the initial object state (oz).
Properties : Type 'lis' of size -1
Real parameters vector
column vector. Any parameters used in the block can be defined here as a column vector.
Properties : Type 'vec' of size -1
Integer parameters vector
column vector. Any integer parameters used in the block can be defined here as a column vector.
Properties : Type 'vec' of size -1
Object parameters list
A Scilab list that defined the list of the Object parameters (opar).
Properties : Type 'lis' of size -1
Number of modes
Number of Right hand side functions in the system.
Properties : Type 'vec' of size 1
Number of zero_crossings
No. of zero-crossings
Properties : Type 'vec' of size 1
Initial firing vector
vector. Size of this vector corresponds to the number of event outputs. The value of the i-th entry specifies the time of the preprogrammed event firing on the i-th output event port. If less than zero, no event is preprogrammed.
Properties : Type 'vec' of size sum(%6)
Direct feedthrough
character "y" or "n", specifies if block has a direct input to output feedthrough.
Properties : Type 'vec' of size 1
Time dependence
Time dependence : character "y" or "n", specifies if block output depends explicitly on time.
Properties : Type 'vec' of size 1
Default properties
always active: no
direct-feedthrough: yes
zero-crossing: no
mode: no
regular inputs:
- port 1 : size [1,1] / type 1
regular outputs:
- port 1 : size [1,1] / type 1
number/sizes of activation inputs: 0
number/sizes of activation outputs: 0
continuous-time state: no
discrete-time state: no
object discrete-time state: no
name of computational function: sinblk
