power factor calculation in matlab

i want to calculate power factor for power measurement.how can i do it in matlab code?

[Star Strider]

It depends on what you are starting with. If you have the current expressed in phasor notation with respect to voltage, it is the tangent of the phase angle.

[David Goodmanson]

which means that if the current and voltage are 90 degrees out of phase then the power factor is infinite, is that correct?

[Star Strider]

Theoretically, since for purely reactive power, no work would actually get done. I doubt this ever occurs in practice, so it is not a concern. (I will leave a detailed discussion of this to those whose power engineering knowledge are more robust than mine.)

[David Goodmanson]

that seems like a good idea, especially since Wikipedia says that the power factor PF has the property -1 <= PF <= 1 ( 0<= PF <= 1 if the device is a load as opposed to a source ).
