I am using regression learning for developing machine learning models. My intention is to save the figure (like residual plot) to a particular working folder. But whenever I click on "Export Plot to a Figure" option, a home directory opens. Then it takes well over 10 seconds for me to navigate to the folder in which I would require to save. This process needs to get repeated everytime, I am trying to save a figure. How to make a working folder open directly for saving?

Thank you for this advice. This would work when we are coding in commandline. Suppose i am using GUI interface for classification and regression learner app, in that case this would not be possible.

"This would work when we are coding in commandline."

And also when writing any code.

"Suppose i am using GUI interface for classification and regression learner app, in that case this would not be possible."

I don't see any reason why not, and you have not explained why you think there is some restriction on its usage (hint: there isn't).

In this case, to change directory with cd() command might be helpful to change the currrent directory to the directory where you wish to save the images.

Thanks for that.

Do NOT use cd for reading/writing data files.

Using cd to access data files is superfluous, slows down code, and makes debugging harder. The MATLAB path is intended for specifying the location of MATLAB code (functions, scripts, classes), and NOT for accessing data files.

The recommended method is to use relative/absolute filenames. All MATLAB functions that read/write data files accept relative/absolute filenames:
