Frequency domain conversion
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 .
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".
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
"??? Error using ==> mtimes
Inner matrix dimensions must agree."
2. Relevant equations
3. The attempt at a solution
T=n*pi/2w where w= omega
%T=n*pi/2w where w= omega
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))
