how to plotting all results when i using for loop
显示 更早的评论
for T_cond = [-100:20:0]
for T_cond = 273.15+T_cond
.
.
.
etc..
m_wf = m_LNG*(h_5s-h_5)/(h_4s-h_4);
m_wf = m_wf + 0;
E_th = (h_2-h_3-h_1+h_4)/(h_2-h_1);
E_th = (E_th + 0)*100;
disp(['E=',num2str(E_th),'%'])
disp(['m=',num2str(m_wf),'kg/s'])
end
end
plot(T_cond,m_wf)
plot(T_cond,E_th)
I want to plot all results in for loop.. but I'm beginner..so It's so hard to me.. Actually This is the first time in my life..help me please

YOu need to reconsider your code..you should not use same index T_cond for the loops.

YOu should do the following to plot figure in a loop.
%%In aloop (not suggested)
figure
hold on
for i = 1:10
plot(rand,rand,'.r')
end
%%suggested and effective
x = zeros([],1) ;
y = zeros([],1) ;
for i = 1:10
x(i) = rand ; % x,y are calculated inside loop
y(i) = rand ;
end
figure
plot(x,y,'-.')

No negative indices in MATLAB.
T_cond = zeros([],1);
m_wf = zeros([],1);
E_th = zeros([],1);
T = -100:20:0 ;
for i = 1:length(T)
T_cond(i) = T(i) + 273.15;
P_eva = refpropm('P','T',T_eva,'Q',0,WF);
h_4 = refpropm('H','T',T_cond,'Q',0,WF);
m_wf(i) = m_LNG*(h_5s-h_5)/(h_4s-h_4);
E_th = (h_2-h_3-h_1+h_4)/(h_2-h_1);
E_th(i) = (E_th + 0)*100;
disp(['E=',num2str(E_th),'%'])
disp(['m=',num2str(m_wf),'kg/s'])
end

I should know the function refpropm with the inputs given. Knowing that only I we can help you.

plot(T_cond,m_wf)
hold on
plot(T_cond,E_th)
Should be inside loop
