edfread2

This is a modification of the File Exchange submission "edfread" for importing an EDF file into MATLAB. I removed a few options which enable import of large files to occur much, much faster in the case of 1-sample records or records containing all of the samples at once.
[hdr, dataMat] = edfread2(fname)

Reads data from ALL RECORDS of file fname ('*.edf'). Header information is returned in structure hdr, and the signals (waveforms) are returned in dataMat, which is either a (samples x channels) matrix, or a (1 x channels) cell array full of (samples x 1) arrays IF there are different numbers of samples in each channel.
