There is an easy way to get phasor representation ?

I have a periodic signal (x,y) with 1000 samples. (like a sin with 1000 samples).

Matlab provides a simple way to get this to a phasor representation ?

I am not aware of a specific phasor notation in MATLAB. Since they are a convenient way of representing complex numbers, leave them as complex variables for calculations and convert them to phasor notation when you output them:

z = 3 + j*5

phasorr = @(z) [abs(z)  angle(z)];                  % angle in radians
phasord = @(z) [abs(z)  atan2d(imag(z),real(z))];   % angle in degrees

phasorr(z)
phasord(z)

I used atan2d in the degree version because in my experience, they do more accurate conversions than multiplying radian angles by (180/pi).

I have made this script which allows users to work with polar phasor representation and plot them easily.

Thank you very much.
