这是一个关于BP神经网络反演数据的一个实例。(an example of data retrieval using BP neural network.)

％ If only 1 output is specified, then dataout (a matrix the same size as ％ data) is returned. The order of t and align is immaterial, as long as ％ the data matrix is input first.( If only 1 output is specified, then dataout (a matrix the same size as data) is returned.
