1. The problem statement, all variables and given/known data Dear all , Am new to matalb and am having some couple of problems. i want to convert the following wave form from time to frequency domain . 1.E=ACos(ωt+φ).[0,T] I have made conversion by using integration by parts.Please find the matlab attached files. ACos(ωt+φ)*exp(-jωt) , limit [0,T] 2. For T=n*pi/2ω where n= odd, how to generate odd values of "n". 3. Graph When ever i try to plot a graph between Amplitude and Time , it generates error or when ever i plot a graph between two variable values e.g T 1:45; Pi 0:360; "??? Error using ==> mtimes Inner matrix dimensions must agree." 2. Relevant equations 3. The attempt at a solution T=n*pi/2w where w= omega function L=laser() %T=n*pi/2w where w= omega w=2*pi*1.93*10^14; phi= 0:360; T=45;% just used to plot a graph L= (-cos(phi)*w*sin(w*T)*exp(-j*w*T))+(w*cos(phi))-sin(phi)*(w*cos(w*T)*exp(-j*w*T)-w+ (w^2)*sin(w*T)*exp(-j*w*T)/(1+w^2)) subplot(1,1,1), plot(phi,L); end Thanks
