correct format for feature matrix in finger print recognition

1 view (last 30 days)
Dear firiends,
In regarding to correct format for feature matrix in finger print recognition, I have a question.
I have 9 finger prints(for 3 persons) which I want to train my network, and I have 3 finger prints for testing(each person one).
After preprocessing and post processing, I could successfully reach to 2 feature of each finger print which are: Termination=[X Y angel] Biorefication=[X1 Y1 Angel1 Angel2 Angel3] both of the matices for each finger print have different row size.
As I told you I have 9 input, in another words, I have 9 inputs which either of them has 2 matrix which I explained above.
Now , I have no idea how I should put these feature in correct format to feed it into neural network?
I am very thankful in advance for your help. Regards,

If you have c classes and N I-dimensional feature vectors
[ I N ] = size(input)
[ c N ] = size(target)
where the columns of target are columns of the c-dimensional unit matrix eye(c).
Hope this helps.
Thank you for formally accepting my answer
Greg
