Hi hello, i am trying to create a CNN model but my inputs are not images, it's a matrix, i would like to know how is it possible to do that, i have searched about it but nothing, and when i am trying to train my network i amm getting this error

Error using trainNetwork

Number of observations in X and Y disagree.

Error in Analyse_Data__CNN (line 81)

net = trainNetwork(D_App,L_App,layers,options);

Thank you so much for helping me i will appreciate it a lot

An image is a matrix so that should not be a problem. It looks like you don't have the same number of labeled ground truth matrices as you have training matrices.

I don't know what kind of deep learning training you're doing but for a standard type you need lots of images that are the same size. The size depends on the network architecture. If your image is a montage of lots of smaller images stitched together, then you get get them as separate images by cropping them out. You can't train a network on only one image!

you're right i totally forgot about this, it's just interpret it as a single image, and as you said you can't train a network on 1 image only, maybe if i make change my matrix to vectors it will make it
