You may want to look at importdata

i downloaded datas from http://www.physionet.org/physiobank/database.. and importdata command is not working for it

[Jan]

Does the file contain binary data? If so, use fread

Answer 2

[Iain]

Try opening the file in notepad, or some other basic text editor and look at the data.

 If its garbled data, its obviously in some binary format.  
 If its csv formatted numbers, try csvread
 If its csv formatted text and numbers use xlsread
 If its some other delimited numbers, try dlmread...
