Introduction

simomex.c

Implements a single output, two input state-space

dynamical system described by these state-space

equations

dx/dt = Ax + Bu

y = Cx + Du

where x is the state vector, u is vector of inputs, a nd

y is the vector of outputs.

stspace.c

Implements a set o f state-space equations. You can

turn this into a new block by using the S-Function

block and mask facility. This example MEX-file

performs the same function as the built-in

State-Space block. This is an example of a MEX -file

where the number of inputs, outputs, and states i s

dependent on the parameters passed in from the

workspace. Use this as a template for other

MEX-file systems.

stvctf.c

Implements a continuous-time transfer function

whose transfer function polynomials are passed in

via the input v ector. This i s useful for continuous

time adaptive control applications.

stvdct.f

Implementsa discrete-time transfer functionwhose

transfer function polynomials are passed in via the

input vector. This is useful for discrete-time

adaptive control applications.

limintc.c

Implements a limited integrator.

vdlmint.c

Implements a discrete-time vectorized limited

integrator.

vlimint.c

Implements a vectorized limited integrator.
