Problems with Matlab Integration

[Harvey]

Hey there,

i experienced problems when trying to use the wfdb toolbox. I tried the installation procedure described in the readme files.

1. My Matlab commands:

clear all;
clc;
close all;
addpath(genpath('C:\Users\Hannes\Documents\MatlabAddOns\wfdb-app-toolbox-master\mcode'));
wfdbdemo
wfdbtest

2. I recieved the error messages:

2.a) for wfdbdemo:

Reading samples ECG signal from MIT-BIH Arrhythmia Database
Reference to non-existent field 'WFDB_CUSTOMLIB'.

Error in getWfdbClass (line 34)
javaWfdbExec=javaObject('org.physionet.wfdb.Wfdbexec',commandName,config.WFDB_CUSTOMLIB);

Error in rdsamp (line 88)
    [javaWfdbExec,config]=getWfdbClass('rdsamp');

Error in wfdbdemo (line 12)
[ecg,Fs,tm]=rdsamp('mitdb/100',1,N);

Error in Test (line 5)
wfdbdemo

2.b) for wfdbtest:
