i have a code below which plot the first curve, please help me to change this code to plot the second curve
显示 更早的评论
beta = 0;
ind2 = 1;
for lambda=0.1:0.01:11.8
lambdai(ind2) = (1./((1./(lambda-0.02.*beta)+ (0.003./(beta^3+1)))));
Cp(ind2)=0.73.*(151./lambdai(ind2)-0.58.*beta-0.002.*beta^2.14-13.2).*(exp(-18.4./lambdai(ind2)));
Ct(ind2)=Cp(ind2)/lambda;
ind2=ind2+1;
end
tab_lambda=[0.1:0.01:11.8];
subplot(1,3,3)
plot(tab_lambda,Cp,'linewidth',1.5)
xlabel('lambda','fontsize',14)
ylabel('Cp','fontsize',14)

What have you tried and where did you have a problem?
HINT: See
doc yyaxis
for some ideas, maybe...

Try this:
fprintf('Beginning to run %s.m ...\n', mfilename);
fontSize = 20
beta = 0;
ind2 = 1;
tab_lambda=[0.1:0.01:11.8];
for k = 1 : length(tab_lambda)
lambda = tab_lambda(k);
fprintf('lambda = %.2f\n', lambda);
lambdai(ind2) = (1./((1./(lambda-0.02.*beta)+ (0.003./(beta^3+1)))));
Cp(ind2)=0.73.*(151./lambdai(ind2)-0.58.*beta-0.002.*beta^2.14-13.2).*(exp(-18.4./lambdai(ind2)));
Ct(ind2)=Cp(ind2)/lambda;
ind2=ind2+1;
end
subplot(2, 1, 1)
plot(tab_lambda, Cp, 'linewidth', 2)
grid on;
xlabel('lambda','fontsize',14)
ylabel('Cp','fontsize',14)
title('Cp', 'FontSize', fontSize);
subplot(2, 1, 2)
plot(tab_lambda, Ct, 'linewidth', 2)
grid on;
xlabel('lambda','fontsize',14)
ylabel('Ct','fontsize',14)
title('Ct', 'FontSize', fontSize);
g = gcf;
g.WindowState = 'maximized';
fprintf('Done running %s.m.\n', mfilename);

The equations you gave do not create a max of 0.36. Are you sure your equations are correct?

After the loop, you can use rescale to rescale the vector
Cp = rescale(Cp, 0, 0.36);
