Save workspace to a specific folder using regular expression

Hello Community,

Im having difficulties with hopefully a simple problem. I have a scripted workflow and at a certain point, I would like to automate the saving of the workspace contents ie variables created etc. to a specific folder that I make earlier in the script. I also want the saved '.m' file to be named after a part of the original image filename that is used in this processing.

I have a line of code that saves to the current folder, but it doesn't save to the location I want, or take the file name I want:

>> save(regexp('defaultFileName','(?<=IMG_)\d+', 'match', 'once'));

The contents of defaultFileName would be similar to: C:\Users\10B\Matlab\Files\Images\*.* , and from an earlier question I asked, I know '(?<=IMG_)\d+', 'match', 'once')' should work for the regular expression element, but no joy.

There is also a variable called new folder, created via:

newfolder = regexpi(baseFileName, '(?<=IMG_)\d+', 'match', 'once');
newfullpath = fullfile(pwd, newfolder);
mkdir(newfullpath);

that makes the folder I want to save the workspace to, and this folder takes the correct name.

So, how can I replicate saving the workspace to the newly created folder, and taking the parsed name from the image name?

Thanks in advance...

 imagename = ... %whatever you use to extract the imagename
 filename = [imagename '.mat'];
 save(fullfile(newfullpath, filename))

Thorsten - excellent thank you! This works perfectly.
