Save multiple figures in one pdf

Question

I am trying to save/combine all the existing figures, created in a loop, in one pdf file instead having multiple pdfs. Let's say one figure per page.

x = rand(5,100); 
y = rand(5,100); 

for i = 1:5 
    plot(x(i,:), y(i,:)); 
    filename_string = ['Plot_Number_', num2str(i),'_' ,'pdf']; 
    print(gcf, '-dpdf', '-r600', filename_string); 
    saveas(gcf,'testx', 'pdf');
end

Answer 1

• Add figure on every plot, this will keep each plot on different window
• Make the filename_string the plot title
• Name the code with the plot, i.e filename.m

---

• Make another m file, let's say main.m
• Use publish(filename', options) to get the pdf file filename.pdf
• Before using publish define the options

options.format = 'pdf'
options.showCode = false

Run main.m and check the current directory you may see an HTML directory where you can find the pdf file named filename.pdf

Code is as follows

---

filename.m

close all
clear
clc
x = rand(5,100); 
y = rand(5,100); 

for i = 1:5 
    figure% keep plots on different windows
    plot(x(i,:), y(i,:)); 
    title(['Plot Number ', num2str(i)], 'color', 'red', 'fontSize', 25)
end

main.m

close all
clear
clc
options.format = 'pdf';
options.showCode = false;
publish('filename.m', options)
