Asked by Michael on 13 Mar 2013

I am trying to set up a phasor viewer, for my own use. I am not getting what I expected as far as the plots are concerned.

What I want is for example **threephasev(10,45)** should give two vectors, one from the origin to (10,0) and the other rotated by 45 degrees.

I might have issues with the ordering in the matrices.

Thank you, Mick

if true function [ output_args ] = threephasev( A,theta ) %threephasev A (magnitude) theta (phase angle) % Plots the phasor of a the phase source % Michael Carey % Student Deakin University % 400100801 % mpc.tab4(nospam)@gmail.com % 12/3/2013

a = [ 0 0 ; A 0 ];

quiver(a(1),a(3),a(2),a(4));

% a(1) % a(3) % a(2) % a(4)

R=[ cosd(theta),-sind(theta) ; sind(theta),cosd(theta)];

b = R*a; hold on quiver(b(1),b(3),b(2),b(4));

end
