this is related to the question asked here:
so I did make to seperate quivers for the inwards and outwards arrows. the new problem is, that some of my arrows that i think should be pointing outwards are pointing inwards.
here is how i created this, tell me where you think i am wrong:
-
-
% find slope of profile
m_profile(2:45, :)=diff(z1)./diff(x1);
m_profile(1,:)=1.7612;
m_profile(29,:)=0;
-
-
%find arrow slope according to m2=-1/m1
m_arrow=-1./m_profile; theta=atand(m_arrow);
-
%create mark vector - indicating which arrows should point inweard(negative cp values)
for j=1:num
for i=1:45
if cp_norm(j,i)<0
mark(i,j)=1;
end end end
k=1; l=1;
flag=[];
nflag=[];
for i=1:45
if mark(i,j)==1
flag(k,1)=x1(i,j);
flag(k,2)=z1(i,j);
flag(k,3)=cp_norm(j,i)*cosd(theta(i,j));
flag(k,4)=cp_norm(j,i)*sind(theta(i,j));
k=k+1;
else
nflag(l,1)=x1(i,j);
nflag(l,2)=z1(i,j);
nflag(l,3)=cp_norm(j,i)*cosd(theta(i,j));
nflag(l,4)=cp_norm(j,i)*sind(theta(i,j));
l=l+1;
end
end
still the result is some of the arrows are pointing inwards as you can see, where am i wrong?
thanks,
Noa
