I import data with uigetfile and then plots that data, then I save the plot to jpg file to a particular folder using print command. Sample is given below. As can be seen in summary report attached it takes about 10 seconds for just 2 graphs. This is very large time spent please suggest some tweak.

print(rawfig,strcat(name,'_raw.jpg'),'-djpeg','-r600')

Also This commands overwrites the file if it exist at that location, How do I prevent it from overwriting and either asking for action or appending some digits in file name.

"This commands overwrites the file if it exist at that location, How do I prevent it from overwriting and either asking for action or appending some digits in file name."

Use dir() to list the files in the current folder. Check if the naem you planned to use exists in the list (ismember() can be used). If the name is used, add a number and check if that file name exists. Repeat until you find a free file name.

OK, not the most efficient, but simple.
