+%DATWRITE Write data to ascii file.

+%	Description
+%
+%	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.
