I have the following functions, created with the help of spline

function c = consumption(v)
load('elbilTesla.mat');
    if any(v < speed_kmph(1)) || any(v > speed_kmph(end))
        error(['Hastigheten måste vara inom intervallet ', num2str(speed_kmph(1)), ' till ', num2str(speed_kmph(end)), '!']);
    else
        c = interp1(speed_kmph, consumption_Whpkm, v, 'spline');
    end
end
function E = total_consumption(x, route)
load(route);
    if any(x < distanceA_km(1)) || any(x > distanceA_km(end))
        error(['Sträckan måste vara inom intervallet ', num2str(distance_km(1)), ' till ', num2str(distance_km(end)), '!']);
    else
        v=interp1(distanceA_km, speedA_kmph, x, 'spline');
       E=integral(@(x) consumption(v),0,x,'ArrayValued',true);
    end
end
