function [xvals,yvals]=fourier(L,nmax,numpoints)
xvals=[];
yvals=[];
for x=1:numpoints
y=0;
for n=1:2:nmax
y=y+(1/n)*(sin((n*pi*x)/L));
end
y=4*y/pi;
xvals=[xvals;x];
yvals=[yvals;y];
end
end
====================================================
[xvals,yvals]=fourier(L,nmax,numpoints);
x = xvals;
y = yvals;
L= 0;
plot(x, y);
I have a function that returns two very long column vectors for xvals and yvals. I'm struggling to create another script that calls upon this function and plots the respective xvals vs yvals. The code below the line gives me an error saying L is not recognized but I don't use it so I'm a bit confused.

You have to define the required input variables first and then call the function.
L = 1. ;
nmax = 100 ;
numpoints = 1000 ;
[x,y]=fourier(L,nmax,numpoints);
plot(x,y);
function [xvals,yvals]=fourier(L,nmax,numpoints)
xvals=zeros(numpoints,1) ;
yvals=zeros(numpoints,1) ;
for i=1:numpoints
y=0;
for n=1:2:nmax
y=y+(1/n)*(sin((n*pi*i)/L));
end
y=4*y/pi;
yvals(i) = y ;
xvals(i) = i ;
end
end
