You can either type this code straight into octave or matlab, or you can save it as a [name_of_file].m and loading it to the software.
octave:1> t= -5:.01:5; octave:2> f=t; octave:3> [ff,tt]=meshgrid(f,t); octave:4> r=exp(j*2*pi.*ff.*tt); octave:5> delta=trapz(r)*.01; octave:6> one1=.001*trapz(delta); octave:7> plot(t,delta);
This is what the graph looks like.
