function datwrite(filename, x, t)
%DATWRITE Write data to ascii file.
% DATWRITE(FILENAME, X, T) takes a matrix X of input vectors and a
% matrix T of target vectors and writes them to an ascii file named
% FILENAME. The file format is as follows: the first row contains the
% string NIN followed by the number of inputs, the second row contains
% the string NOUT followed by the number of outputs, and the third row
% contains the string NDATA followed by the number of data vectors.
% Subsequent lines each contain one input vector followed by one output
% vector, with individual values separated by spaces.
