training and testing image data with neural network tool in MATLAB

Question

My original pictures are gray scale 200x200x3.

1. I have downscaled them to 50x50x3.

2. They are mug shots of 100 different people. I have taken the copy of 30 of them, and corrupted, and put back in the same image matrix cell, and it became 130 pictures.

3. Afterwards, I have created a 130x7500 array which involves each picture as a row. Then, I have classified that matrix into training and test data set. Then, classified the divided data using MATLAB decision tree tool, and knn tool. Now my question is, how to manage it by using neural network tool.

4. And I have a classification matrix 130x1.

If I want to do the same thing using neural network tool, what I should do?
