Matlab下的EEG处理程序库

function [volt] = eeg_load_ascii(filename)
% EEG_LOAD_ASCII - Load ascii EEG data matrix
%
% Assumes a simple matrix format of data, compatible with matlab
% 'load' command, with no strings (eg, labels) in the data file
%
% Useage:   [volt] = eeg_load_ascii(filename)
%
% where:    filename is the full path + fileprefix + filextension
%
% comment:  A very simple function, useful in other scripts.
%           Could be developed further to include matrix orientation
%           checks and/or reorientation options.  Currently a simple
%           wrapper for the 'load' matlab function.
