Matlab Help

I'm having trouble importing .dat files into Matlab. Any help doing this?

The signal .dat files are found in the link below

OBJECTIVE: To introduce analysis of the heart in MATLAB. PROCEDURE: 1. Before loading signals download this toolkit. 2.Download the following signals from the PhysioNet Database (ptbdb): a. Normal: patient104/s0306lre and patient105/s0303lre b. Myocardial Infarction: patientl/s0010_re and patient2/s00151re c. Hypertrophy: patient212/s0434 re 3. Use the following code to extract the signals: fileName = [ 'ptbab/patient ' , num, ' / ' , trial] ; wfdb2mat (fileName) This will create a *.mat file for the corresponding signal Note: The path to the toolkit should be an added path 4.Use a 0.05-40 Hz bandpass filter to filter the signal (Note: see butter0 and filtfilt0) 5. Create a graph of 5 seconds of each signal displaying the QRS of at least one cycle (Note: see 6.Calculate the heart rate of each subject WHAT TO TURN IN: Turn in a pdf of the graphs and heart rates of each subject (save as Lab4.pdf). Also, turn in the MATLAB file (save as Lab4.m) peaks0) only plot j, ii, and iii of each signal OBJECTIVE: To introduce analysis of the heart in MATLAB. PROCEDURE: 1.
