Hi! I am trying to plot a fourier function by using fplot but I am getting the following error.
The following error was reported evaluating the function in FunctionLine update: Unable to convert expression containing symbolic variables into double array.
Apply ‘subs’ function first to substitute values for variables.
syms f(t) g(t) w;
x=@(t)heaviside(exp(-20*t));
h=@(t) heaviside(12.*t.*exp(55*t));
xf=vpa(fourier(f,t,w));
hf=vpa(fourier(g,t,w));
fplot(@(w) abs(hf), [-20*pi 20*pi])Hi! I am trying to plot a fourier function by using fplot but I am getting the following error.
