What does the error "Error using bsxfun" mean in implementing FFNN?

Hello, I'm new to ANN and I was trying to implement FFNN using the following code:

a = xlsread('Data.xlsx'); 
input = [a(:,3) a(:,4) a(:,5) a(:,6)]; 
target = a(:,8); 
net = feedforwardnet(10);
net = train(net, input', target'); 
y = net(input);

But it gave me the following error for the last line:

Error using bsxfun
Non-singleton dimensions of the two input arrays
must match each other.

What does this error mean and how can I fix it? Is it because there are missing attributes in the feedforwardnet()?

size(input) = 108 × 4 
size(target) = 108 × 1

Answer 1

[Greg Heath]

The input matrix of N I-dimensional "I"nputs and corresponding output target matrix containing N O-dimensional "O"utputs have the dimensions

 [ I N ] = size(input)

 [ O N ] = size(target)

What are the results of these commands for your data?

Hope this helps.

Thank you for formally accepting my answer
