how to index output figures

Hi, I am working with jpeg pictures when I'm editing them in a cycle. And I'd like to create output something like 'Pic_1.jpg', 'Pic_2.jpg',... depending on number of iteration. So I wanto to ask you how to create figures with variable index. Thanks

See the FAQ : http://matlab.wikia.com/wiki/FAQ#How_do_I_save_my_figure.2C_axes.2C_or_image.3F_I.27m_having_trouble_with_the_built_in_MATLAB_functions., which basically recommends to use export_fig to save your figures or axes as picture files.

Then put export_fig into a loop like is in the FAQ:

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

which shows you how to create a filename based on the iteration variable.
