## DLTISIM

Simulates a discrete-time LTI state-space system.

## Syntax

`y = dltisim(A,B,C,D,u)`

`[y,x] = dltisim(A,B,C,D,u,x0)`

## Description

This function simulates a discrete-time LTI state-space system. The model structure is the following:

An optional initial state can be specified.

## Inputs

`A,B,C,D` is the discrete-time LTI state-space system matrices.

`u` is an *N* x *m* matrix conatining *N* samples of the *m* inputs.

`x0` is the (optional) initial stae. an *n* x *1* vector.

## Outputs

`y` is the computed output sequence, an *N* x *l* matrix.

`x` is the (optional) computed state, an *N* x *n* matrix.

## Algorithm

A direct iteration of the system's state-transition equation is used to obtain the state-trajectory for all time-instants. The function `ltiitr` is used to this end.
