Hi,
I want to draw a graph and its origin must be in the upper left corner of output. The numbers should increase positively down the y-axis. How can I do this?
Thanks

x = 1:13; y = 2*x+3;
plot(x, y, 'r*--'), grid on
set(gca, 'YDir','reverse'), xlabel('x'), ylabel('y')

syms z
y1=3*z^3+2 % Ve tu 0 den 10 Plot this graph from 0 to 10; starting position is 0
y2=3*z^4+2*z^2+6 % Ve tu 10 den 25 (0-10-10-15) Plot this graph from 0 to 15; starting position is 10
L1=10
L2=15
Xtong=linspace(0,L1+L2,20) % Chia thanh 20 doan boi 20 diem de cbi ve cho tat ca
Yt=zeros(1,20)% Tao ra de ve cac diem chia tren z cua tat ca cac doan i
X2=linspace(0,L1,100); % Chia doan 1 thanh 100 diem de ve do thi cho doan 1
A2=subs(y1,z,X2) % Nhan gia tri tai 100 diem de ve do thi cho doan 1
plot(Xtong,Yt,'Linewidth',1) % X tong la tong chieu dai de xac dinh chieu dai truc Z khi ve
hold on
plot(X2,A2,'g','Linewidth',4) % Do thi doan 1
Xve2=linspace(10,25,100); % Chia thanh 100 diem cho doan i=2 tro di
XXX2=linspace(0,L2,100)
B2=subs( y2,z,XXX2) % Nhan 100 gia tri de ve duong do thi
plot(Xve2,B2,'r','Linewidth',4); % Ve do thi
xlabel('Duong truc Z');
