I am trying to plot the symbolic function:
I have expressed the function using syms for f(x),x,n
the trouble I am having is with x, x is a value from 0<x<L. where L is a arbitrary number. 100 for example.
how would I plot 0:L on the x axis and the function of f(x) on the y axis. for each n.
thank you for the help.
heres what I got so far with my script

Ran in:
Is the really the function you calculated the Fourier series of ?
L = 10;
nx = 100;
nmax = 200;
x = (linspace(0,L,nx)).';
n = 1:nmax;
f = ((-1).^n-1)./(n.^2*pi) .* cos(n.*x) + (1-2*(-1).^n)./n .* sin(n.*x);
values = -pi/4 + sum(f,2);
plot(x,values)
