i am trying to caluculate 'W' at angles between 0-60 degrees. im not sure how to create a loop function that will allow me to continuously calculate this output whilst varing the angle. I tried using 'theta = 0:60' but that caused an error. my code so far:
theta=(0:60);
w_s = 10; % angular velocity of spin
a_s = 6; % angualar acceleration of spin
w_n = 3; % angular velocity of nutation
a_n = 2; % augalar acceleration of nutation
w_p = 5; % angular velocity of precession
a_p = 4; % angular acceleration of precession
%% Geometry values
rA = [0 7.4103 7.1651];
%% vectors
vw_s = [0 w_s*sind(theta) w_s*cosd(theta)];% spin vector
vw_p = [0 0 w_p]; % precession vector
vw_n = [-w_n 0 0]; % nutation vector
%% Angualar velocity
wi = [-w_n 0 0]; % i component of W
wj = [0 w_s*sind(theta) 0]; % j component W
wk = [ 0 0 (w_p + w_s*cosd(theta))]; % k component of W
W = wi + wj + wk; % Angular Velocity;

You need to make wi vector the same size as wj and wk
wi = [-w_n+theta*0 0 0]; % i component of W
