Magnitude and Phase of a Transfer Function (mag_phase)

Magnitude and phase of a transfer function (i.e. linear system) at a specific point in the frequency domain.

mag_phase

Magnitude and phase of a transfer function (i.e. linear system) at a specific point in the frequency domain.

Syntax

[mag,phase] = mag_phase(sys,x)
[mag,phase] = mag_phase(sys,x,units)

Inputs

• sys (1×1 tf, zpk, or ss): continuous or discrete-time linear system
• x (1×1 complex double): location in frequency domain
  • in continuous domain
  • in discrete domain
• units (char array): deg or rad

Outputs

• mag (1×1 double): magnitude of transfer function at or
• phase (1×1 double): phase of transfer function at or
