Saving a file in a relative directory on the current .m file.

I am having trouble setting up a save file folder. It just seems to save my file to whatever my current directory is. Is it possible to save in a certain location relative to the .m file that I run. The file that I run is deep withing my folder structure, and I want to save it a folder back with current date. I tried using mkdir() but that would just make folders anywhere my current path was. I also tried using CD to my path location but it just seems to be ignored and it starts saving anywhere. One thing that I also see is repeating folder structures where my code basically recreates the entire two folders within my directory. Any solution to this Problem?

Then use an absolute path. You can use fullfile for that. If it needs to be relative to the m-file, you can use the following syntax of which

str = which(item)

to get the path of the m file. Then use that as an input to fullfile to build up the desired save path. This assumes your m file is on your path.

Awesome! Thanks for the great solution.

Yes, relative paths are possible

• ./folder/file.m save path begins in the current folder
• ../folder/file.m save path begins in the parent folder (up one level)
• ../../folder/file.m save path begins in the parent of the parent folder (up two levels)

I understand what relative path is but I want to setup it up in a way that I don't need to be in the current folder. The code saves it relative to where .m file is being executed.

Relative to where the m-file is being executed

Is this not your current folder?

[Zarif Rahman]

It is not actually. The folder structure has my .m file deep within and I have to run it from the outside when I add all of my folders and subfolders.

This is where my .m files are located but I am usually near my CodeBase2 folder. Is it possible to do this? Or am I out of luck?

Wow awesome! This solves my issue and it's almost there but I'm having a hard time CD ing to the area. I can't seem to go back a folder or even CD to the area. It just nets me an error stating that the name is non-exisitent or the directory is not there.

Please share the full error message (all the red text) and the code you are using.

I was able to have it fixed. I just replaced the extraneous words on the string to make it work.

Can I make sure your comment with the which keyword is the solution to the question I asked here. I feel this will help people who are having the same issue.
