How can I use Matlabs import feature to read signal files?
You can’t in general, because Matlab doesn’t know how to figure out which of the many supported formats is used in any given signal file, because it can’t understand the most commonly used formats in any case, and because (in many cases) signal files are orders of magnitude larger than any matrix that Matlab can handle. You can export a segment of signal files up to a million samples in length as a .mat file readable by Matlab or Octave, using the PhysioBank ATM. Longer segments may be difficult to handle, but you can make them if you wish using wfdb2mat, included in the WFDB software package and used by the PhysioBank ATM. The .mat files produced in this way can be read and plotted using plotATM.m. See How can I read signal files? for a variety of other ways to read signal files from Matlab without using its import feature. Top How can I use Excel’s import feature to read signal files?
