I have around 30000 excel files that contain information of different signals My main goal is to classify those signals into 2 classes. I have two problems, How to load all the files on the matlab and acquire this data knowing that each file characterizea window of my signal by a dozen values, every file looks like that: (see the attached file)
And then I want to collect the data from each file and do a supervised learning And classify the 30,000 files into two classes (one thing A happened to the signal or two thing did not happen) How can I do that ? Need help ??

See xlsread() and readtable(). These function can load the data from an excel file into the workspace. You will need a for loop to read and extract data from all the file. Refer here for the procedure to read all excel file one by one. After the data is loaded into the workspace, you can apply your learning algorithm.
