Function File: sys = c2d (sys, tsam, method)
Function File: sys = c2d (sys, tsam, 'prewarp', w0)

Convert the continuous LTI model into its discrete-time equivalent.

Inputs

sys

Continuous-time LTI model.

tsam

Sampling time in seconds.

method

Optional conversion method. If not specified, default method "zoh" is taken.

’impulse’

Impulse Invarient transformation.

’zoh’

Zero-order hold or matrix exponential.

’foh’

First-order hold, linear approximation of the input signals between two sample times

’tustin’, ’bilin’

Bilinear transformation or Tustin approximation.

’prewarp’

Bilinear transformation with pre-warping at frequency w0.

’matched’

Matched pole/zero method.

Outputs

sys

Discrete-time LTI model.
