Calculation of frequency from workspace (offline)

Hello,

I would like to measure the frequency of three-phase voltage from the data saved in workspace, post simulation. I dont want to use PLL as it slows my simulation. Can you please suggest how to do it ?

Thanks!

you can use spectrum analyser in dsp system toolbox.

Probably best to use fast Fourier transform function in MATLAB.
