So I two figures, one is the background and one is the plot line. How can I save them all in one figure?
imshow(averaged_bw1);hold on
plot(interp1((1:n)',re,(1:n)','pchip'),rowx, 'b-', 'LineWidth', 2);
recDir = fullfile('C:\','Users','User','Documents','MATLAB',cas,strrep('carmeri','i',int2str(num_carmer))...
,strrep('linetracki','i',int2str(num_photo)));
mkdir(recDir);
imwrite
(averaged_bw1,re,[recDir,'\',strrep('linet','t',num2str(numt)),'.png']);%what code should I write in this part
I'm going to save the figure like this

Try exportgraphics() if you have R2020a. Otherwise use export_fig().

Hey, I think you need to use the 'imwrite' command instead of 'imwrit'.
If it is a typo, you can refer to this answer to save the image at your desired directory with the name you want.

Please go through imwrite documentation as well

imwrite() won't work unless the blue has been burned into an RGB image.
