If you are successfully processing one image and retrieving the variable(s) you want from it, simply place this code inside a loop that iterates over files in your directory. See:
help dir
help for

At each iteration of the loop, insert these variables into an array. When your loop is finished, you can save this array of variables as a mat file. See:
help save

Thanks,
Sven.

Processing a list of files is 4.12 in the FAQ.

files.3F
You can look up the documentation for load() to see how to save into
a .mat file.
