I have written a code to generate several plots from an array of data. Whenever I am trying to save those image files by savefig (for .fig Matlab files) or by saveas as jpeg or eps format, the saving of the image files is inconsistent. For a group of plots, savefig('FileName.fig') and saveas(gcf,'FileNameeps','eps') are working, i.e., images are saved in the current folder. However, sometimes the newly generated plots are not overwriting the previously generated plots (for some other runs) in the folder.

I have tried including the following before each plot:

delete FileName FileNameeps

But the problem persists. Only when I manually delete all the previous image files from the previous runs for the current folder, newer plots are saved. What can be a fix? Such problem did not occur when I had to generate fewer plots (as in codes generating one dozen plots in stead of some 4 dozen plots)

Thanks in advance.

I sort of managed the situation following Ninad's advice. But I would like to knoe the cause of the issue, as it had not cropped up before. Has anybody else faced such issues?

deleteFig.m

Hi Amritesh,

I recommend running a check to delete the image file if it already exists in the current working directory before saving the new plot using the same name. This approach helps in avoiding any potential issues with file overwriting.

To assist you with this, I've attached a dummy script named "deleteFig.m" that performs this task.

I hope you find this helpful.

Regards,

Ninad

Thanks Ninad for your response. Following your cue, I went through the MATLAB help section and feel isfile is a more suitable function, at least that is what MATLAB recommends. I entered all the files as a string and perform a loop search and delete operation to take care of my problem, as you had suggested in the dummy file.

Thanks.
