Generic block

### Block Screenshot

### Contents

### Palette

### 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.

### Dialog box

**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

**Iutput port sizes**Number of regular input 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 dependance : character "y" or "n", specifies if block output depends explicitly on time.

Properties : Type 'vec' of size 1
