Googled 'Back propagation algorithm matlab' and this was the first result: http://anoopacademia.wordpress.com/2013/09/29/back-propagation-algorithm-using-matlab/comment-page-1/

[Sansri Basu]

the code shows error in line 7 as: 'Input argument "Input" is undefined.'

[Niklas Nylén]

See the first line of the code:

 function BackPropAlgo(Input, Output)

This means that you need to call the function with your input data and expected output data. What should it train towards otherwise?
