How to save a plot with the name of the file

Hi,

I'm a beginner on Matlab.

I have a script that read an excel table, does some operations and plots 3 different figures.

What I would like to do is to save each figure with a different name, made of the script's name + _Fo (for example). So if scripts are named file1, file2 and file 3, I want figure 1 to be named file1_Fo, figure 2 as file2_Mn and figure 3 as file3_Ni. The name of the script and the name of the excel table are the same!

How could I do that?

I've tried with something like that

saveas(fig(1), sprintf('_Fo.jpg', 1))

But i don't know how to put the name of the file automatically in front of _Fo.

Thank you

Alberto

Use the strcat function. For example...

x = [2 4 7 2 4 5 2 5 1 4];
bar(x);
saveas(gcf,strcat('file',num2str(ii),'_Fo.jpg')) % Where ii would be the number you want (e.g. you could make a loop so it is not hard coded).

Thank you but I don't understand it!

Let's say that I have a script (e.g called MyTest) that produces 3 different figures.

How do I save them automatically with a name like MyTest_Fo, MyTest_Ni and MyTest_Mn?

I would like a way to automatically get the script's name + _Fo, without manually type the script's name!

I don't know if you see what I mean!

Cheers!

Use the mfilename function:

M = mfilename();
C = {'Fo','Mn','Ni'};
for k = 1:3
    F = sprintf('%s%d_%s.jpg',M,k,C{k})
    saveas(fig(1),F)
end
