Dear friends

I am working on an image processing project using ANN networks,the network is trained via "nftool".in the nftool process

i select to have sample rows,so i have 56 sample of 66 elemnts. after training the network i use "gensim" command to create the simulink model. when i want to put the image into the network, which is a 56*66 pixel image, the simulink error says that it should be a 66 element signal, so my problem is how to seperate 56 row of 66 element to enter to the neural network seperatly
