It is not an ascii file to use load, it is binary file. You have to use fread to read the file. YOu can use fread on knowing the format of the file.

It would probably help more if you would read the supporting information at the site on how to use the data files... <physionet.org faq>

To get the database you want, scroll down to ‘Stress Recognition in Automobile Drivers (drivedb)’, then using the Toolbox drop-down menu, download it as a ‘.mat’ file. First, be certain that you have chosen the Record, Signals, Annotations (if applicable), Length, Time format, and Data format you want.
To illustrate:
Scroll down and find the link to the database you chose. Right-click on it to download it.
You can then load it into your MATLAB workspace as you would any other ‘.mat’ file.
I always recommend using the load function with an output argument, so you can see and choose what variables you want to import into your workspace. It also allows you to assign your own variable names to the data, so any in the ‘.mat’ file do not overwrite any similarly-named variables already in your workspace.
If you are going to use Physionet frequently, please take a few minutes to explore it. That will be time well spent.
