# scicos_state

Define a state structure

### Module

### state

States of the model, that is, everything than can evolve during the simulation.

Type : scilab tlist of type `"xcs"`

with fields :
x,
z,
oz,
iz,
tevts,
evtspt,
pointi and
outtb.

#### x

The continuous-time state register, which is obtained by concatenating the continuous-time states of all the blocks.

Size : total of all the size of continuous-time state registers.

Type : column vector of real numbers.

#### z

The discrete-time state register, which is obtained by concatenating the discrete-time states of all the blocks.

Size : total of all the size of discrete-time state registers.

Type : column vector of real number.

#### oz

The list of the object discrete-time state, which is obtained by concatenating the object discrete-time states of all the blocks.

Size : total of all the size of object state.

Type : list of scilab object.

#### iz

Vector of size equal to the number of blocks.

That vector is used to store pointers of the working state register (work). If a block needs to allocate memory at initialization (flag 4), the associated pointer is saved here.

Size : number of blocks.

Type : column vector of real numbers.

#### tevts

Vector of size equal to the number of activation sources. It contains the scheduled times for programmed activations in evtspt.

Size : number of activation sources.

Type : column vector of integers.

#### evtspt

Vector of size equal to the number of activation sources. It is an event scheduler.

Size : number of activation sources.

Type : column vector of integers.

#### pointi

The number of the next programmed event.

Size : 1.

Type : integer.

#### outtb

Scilab list containing all output registers of blocks. Each element of that list contains typed matrix-based data.

Size : number of regular output ports.

Type : list of scilab matrix.
