Error in ROOO (line 6)

subplot (321);

2. Second error

Error in isequal3 (line 141)

f_x = find (x);

Error in isequal (line 30)

retval = isequal3 (0, x, varargin{:});

Error in matlab.uitools.internal.uimodemanager/unregisterMode (line 11)

if isequal(allRegisteredModes(i),hMode)

Error in matlab.uitools.internal.uimode>localReparentMode (line 224)

unregisterMode(hManager,hThis);

Error in matlab.uitools.internal.uimode/set.ParentMode (line 178)

obj.ParentMode = localReparentMode(obj,value);

Error in matlab.uitools.internal.uimode/registerMode (line 9)

hMode.ParentMode = hThis;

Error in uimode (line 117)

hObj.registerMode(hMode);

Error in plotSelectMode

Error in getProxyValueFromHandle (line 25)

hMode = plotSelectMode(hFig);

and there is many. when i want to use any tool

This is rather obfuscated code:

par = 2*find(strncmpi('Parent', pvpairs(1 : 2 : end), 6));

What is its purpose? Why compare every 2nd character: is this an attempt to match some multiple-byte character encoding that has been incorrectly imported?
