The purpose of this code is to help beginners understand the programming details of CNNs
This code is the main function that you can run this network. I also provided a trained network in Accuracy_Calculation.m and you can run that code to calculate the train_set or test_set's accuracy.
I mainly refer to Andrew Ng's deeplearning.ai and some online blogs(https://www.cnblogs.com/pinard/p/6494810.html)
If you have any question or find any mistake in this code, please do not hesitate to contact me immediately (peng_sun0819@163.com)
