How to plot fourier transform in matlab? These are the MATLAB commands for computing fourier transform and for plotting the transform - syms t y f = fourier(5*cos(2*pi*1000*t),t,y) ///// When you run these 2 commands above in MATLAB, the Fourier Transform is displayed as output. The output that
Fourier Transform (matlab)? >> clear >> t=[-2:0.01:2]; >> g=sqrt((t.^2)-4); >> plot(t,imag(g), 'r'); >> hold on >> plot(t,imag(fft(g)), 'b'); Not sure exactly what your problem is asking, but this might do it. I just use the built-in Fourier transform of Matlab. I assume you don't h
MATLAB and Fourier Transform - California State University, Northridge Last semester we used the fast Fourier Transform algorithm in MATLAB to investigate data sets. ... Recall, that the vector p1 is symmetric about N1/2 (why?), and that is why we only plot the first half of this vector. Answer the following questions about
