MatLab does not like my function. It says I need an 'end', but I have one.

function drawbox(v0,v,width,color)
box=zeros(2,6);
tmp=hypot(v(3)-v0(3),v(1)-v0(1));
if  tmp > 1e-8
    p=[v(3)-v0(3),0,-(v(1)-v0(1))]/tmp;
    box(:,1)=[v0(3),v0(1)];
    box(:,2)=[v0(3)+p(3)*width,v0(1)+p(1)*width];
    box(:,3)=[v(3)+p(3)*width,v(1)+p(1)*width];
    box(:,4)=[v(3)-p(3)*width,v(1)-p(1)*width];
    box(:,5)=[v0(3)-p(3)*width,v0(1)-p(1)*width];
    box(:,6)=[v0(3),v0(1)];
end

Is this function saved in a separate m file ? Or inside an m file with a different name ?

yes

Your if statement is closed by an end, but the function statement needs one as well, in certain circumstances.

function drawbox(v0,v,width,color)
    box=zeros(2,6);
    tmp=hypot(v(3)-v0(3),v(1)-v0(1));
    if  tmp > 1e-8
        p=[v(3)-v0(3),0,-(v(1)-v0(1))]/tmp;
        box(:,1)=[v0(3),v0(1)];
        box(:,2)=[v0(3)+p(3)*width,v0(1)+p(1)*width];
        box(:,3)=[v(3)+p(3)*width,v(1)+p(1)*width];
        box(:,4)=[v(3)-p(3)*width,v(1)-p(1)*width];
        box(:,5)=[v0(3)-p(3)*width,v0(1)-p(1)*width];
        box(:,6)=[v0(3),v0(1)];
    end
end
