Matlab下的EEG处理程序库

function eeg_write(file,data,PRECISION)
% EEG_WRITE - Write matrix of EEG data into binary file
%
% Useage:   eeg_write(file,data,PRECISION)
%
% where:    'file' is the path + filename, eg "c:\data.dat"
%           'data' is a matlab variable
%           'PRECISION' is a binary format ('double' default, see fread)
%
% comment:  Uses the fwrite method to output both 'size(data)' and
%           data. The size(data) integers are written first and used
%           by 'eeg_load' to determine the size of the data matrix.
%           All files are 'ieee-le'.
