Hi, I'm a new user of Matlab and trying to create a neural network with the nntool as it is much easier with this interface. While I can load many inputs and targets, when I want to create the network I am having a problem loading multiple inputs and targets at the same time (there is the option of loading only one), for ex. with back-propagation. I would really appreciate any help thanks in advance

The following code import 4 columns as inputs, and 1 column as output
may you can modify as your own dataset
inputs = xlsread('D:\MyData\data.xls', 1, 'A2:D115');
targets = xlsread('D:\MyData\data.xls', 1, 'L2:L115');
inputs=inputs';
targets=targets';

There is may way to load your data before using nntool
the following URL shows how to load data from text file

after that you can use nntool

Hi, thanks for the quick response. Though, I have already imported my data from an excel file, which are different columns of the xis and yis. I cannot have them as parallel inputs and outputs of the Network I "create" with the nntool. Any ideas?
Thakns!

Yes! Well, the dataset is imported from an excel file with 4 columns: x1,x2...x4 (which I want to be 4 different inputs at the same time of the neural network) and 3 columns: y1, y2, y3 (which I want to be outputs of the network). However, while I create the network with the nntool, with back-propagation, there is only otion of one input and target data at a time. This is my problem
