Several reason why a user would want to do that include: *Users who are in an unsupported architecture (such as 32 bit systems etc) *Users who want to test on an older version of the WFDB library *Users who wan to test on a new version of the WFDB library that has not yet been deployed with this toolbox Users should compile the WFDB binary and put them in their respective folder: bin lib lib64 An example is provided in this folder that was build on Linux Debian Wheezy. You can use the Makefile in this directory as a starting point for compiling all the necessary targets on your architecture or version of WFDB. Once the code has been compiled. Please make sure that you set the flag: 'use_custom_nativlib=1' In the /mcode/wfdbloadlib.m function to true in order to load these native applications.
