function points=refine(x1, x2, tol)
xm = (x1+x2)./2;
if abs((f(x1)+f(x2))./2-f(xm))<tol
points=[x1,x2];
else
left=refine(x1, xm, tol);
right=refine(xm, x2, tol);
points=[left, right(2:length(right))];
end
end
function linearinterp
x=linspace(-5, 2*pi, 30);
y=exp.^(-x./2).*sin(x^.2+8);
points=refine(0, 7, 0.1);
plot(x, y, points, f(points), 'r+');
hold on
plot(points, f(points));
hold off
end

How are we supposed to know? no error message, no details about how you ran your two functions ...

You cannot just press F5 or click on "run". You need to go to the command window and call the function like you were putting it into a program. For example,
refine(1.343, 83.60, 1e-6)

exp.^(-x./2) is not proper. exp is a function, not the value "e", so it must be immediately followed by a left parenthesis: exp(-x/2). You do not need the dot before the slash because 2 is a scalar, not an array.
