Export Figure using Print

I (want to) use the print command for exporting a Figure (here: f1) using the following code:

print -f1 -dpng -r600 \\folder\subfolder1\filename

It works quiete good, however, I would like to manipulate the file location, for example, a loop where the file ist exported to subfolder2, subfolder3 and so on. It seems that everything behind print is a string. Unfortunately, "normal" string manipulation like the following is not working here,

for i=1:5 print .... '\\folder\subfolder',num2str(i),'\filename' end

Is there any option to overcome this? P.S. I do not want to swap from print to another export command, because it took a lot of time to make all the figures look good as tehy do now (with the rigth font and fontsize,...)

Appreciate help.

This might help:

You could use the same to write sequence of files

http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

Instead of reading files, you have to write sequence of directories ..

I'm on a mac and so this works for windows you might want to change the / to \ to traverse the directory

for ii=1:3
    savedir=strcat('new',num2str(ii));

      mkdir(savedir);

      newname=[savedir '/' 'image.jpg'];
      h=figure;
      plot(1:4*ii)
      saveas(h,newname);
  end

Matlab's makedir() command might be more convenient than calling a system function.

true, Thanks Jan, I forgot about it.. Edited accordingly

ii = 1;
print('-f1', '-dpng', '-r600', sprintf('\folder\subfolder%d\filename', ii));

The functional form of commands is safer, because the interpretation of the abbreviated form without parenthesis depends on the Matlab version. Example:

Ok in 2009a:

fullfile * *

Fails in 2009a, but works in older versions:

fullfile * p

Fails in 2009a:

strcat * 2    % Error using STRCAT: not enough input arguments
strcat * _    % Error: the input character is not valid

But this works:

strcat 1 * 2   % '1*2'
strcat a _     % 'a_'

Thanks for the answer. It looks interesting but it leads to the error: Error using name (line 104) Cannot create output file 'c:\older.png'

Error in print (line 206)
    pj = name( pj );

Error in Auswertung_3D_2p9_temp (line 399)
print('-f1', '-dpng', '-r600', sprintf('c:\folder\subfolder%d\filename', ii));

Do I make something obvious wrong? Furtheremore, beside a single variable, it is interesting how it would look like with more variables.

[Jan]

The filename in the error message "'c:\older.png'" is not compatible to the posted code. Do you have write permissions on C:\ ?

What does "more variables" mean? For the usage of sprintf see:
