I think you should show the relevant part of your code.

well... not without a bit of ML code...

hehe.. changed of mind. i didnt use evalin anymore. just using simple loading style. like this

load ('np1-20mfcc5st8mix50ms.mat','priornp');
load ('np2-20mfcc5st8mix50ms.mat','transmatnp');
load ('np3-20mfcc5st8mix50ms.mat','munp');
load ('np4-20mfcc5st8mix50ms.mat','Sigmanp');
load ('np5-20mfcc5st8mix50ms.mat','mixmatnp');
load ('pp1-20mfcc5st8mix50ms.mat','priorp');
load ('pp2-20mfcc5st8mix50ms.mat','transmatp');
load ('pp3-20mfcc5st8mix50ms.mat','mup');
load ('pp4-20mfcc5st8mix50ms.mat','Sigmap');
load ('pp5-20mfcc5st8mix50ms.mat','mixmatp');
load ('PAIN20MFCC50ms','data_pain1');
load ('NONPAIN20MFCC50ms','data_nonpain1');

and i execute this :

testlogliknpVSnp=zeros(handles.Fs,1);
testloglikpVSnp=zeros(handles.Fs,1);
for i=1:handles.Fs
testlogliknpVSp(i)=mhmm_logprob(data_pain1(i),priornp,transmatnp,munp,Sigmanp,mixmatnp);%NOPAIN MODEL
testloglikpVSp(i)=mhmm_logprob(data_pain1(i),priorp,transmatp,mup,Sigmap,mixmatp); %PAIN MODEL
if testloglikpVSp(i) > testlogliknpVSp(i)
set(handles.verification,'String','this cry belongs to pain class')

testlogliknpVSnp(i)=mhmm_logprob(data_nonpain1(i),priornp,transmatnp,munp,Sigmanp,mixmatnp);% non-pain model
testloglikpVSnp(i)=mhmm_logprob(data_nonpain1(i),priorp,transmatp,mup,Sigmap,mixmatp); % pain model
if testlogliknpVSnp(i)> testloglikpVSnp(i)
set(handles.verification,'String','this cry belongs to no pain class');
end
end
end

and now, new error, it prompt: index exceed matrix dimension.
knows whats solution for this? :)

Instead of doing this, I recommend that you call LOAD with an output
argument. Then you can either create variables that contain the contents of
the fields of that struct array, or you can directly refer to the fields
themselves in your code.

Yes -- debugging. Set a breakpoint in your code (or use the "Stop if
Errors/Warnings" item on the Debug menu) and run your code, then determine
where you're trying to index into an array using an index that's too large.
Once you know _where_ the problem lies, you can work on figuring out how to
fix it.

steve, now the error has gone. thank you. but i my code did not work properly.
this is my full code. **frankly, i dont know how to load with output argument. hehe. thats why im sticking with --> load ('np1-20mfcc5st8mix50ms.mat','priornp');**

function varargout = file2(varargin)
% Begin initialization code - DO NOT EDIT
gui_Singleton = 1;
gui_State = struct('gui_Name', mfilename, ...
'gui_Singleton', gui_Singleton, ...
'gui_OpeningFcn', @file2_OpeningFcn, ...
'gui_OutputFcn', @file2_OutputFcn, ...
'gui_LayoutFcn', [] , ...
'gui_Callback', []);
if nargin && ischar(varargin{1})
gui_State.gui_Callback = str2func(varargin{1});
end

if nargout
[varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
gui_mainfcn(gui_State, varargin{:});
end
% End initialization code - DO NOT EDIT


% --- Executes just before file2 is made visible.
function file2_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
handles.fileloaded = 0;

% Update handles structure
guidata(hObject, handles);

% --- Outputs from this function are returned to the command line.
function varargout = file2_OutputFcn(hObject, eventdata, handles)
varargout{1} = handles.output;


% --- Executes on button press in Selection.
function Selection_Callback(hObject, eventdata, handles)
[filename,pathname] = uigetfile({'*.wav'},'pick a file');
set(handles.edit1,'String',{filename},'Value',1)
[x,Fs] = wavread([pathname '/' filename]); %
handles.x = x ./ max(abs(x))
handles.Fs = Fs
fileloaded = 1

guidata(hObject,handles)

function edit1_Callback(hObject, eventdata, handles)
a = num2str(get(handles.Selection,'String',{filename}));
set(handles.edit1,'String') = a;

guidata(hObject,handles)

% eventdata reserved - to be defined in a future version of MATLAB
% handles empty - handles not created until after all CreateFcns called

% Hint: edit controls usually have a white background on Windows.
% See ISPC and COMPUTER.
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
set(hObject,'BackgroundColor','white');
end


% --- Executes on button press in verify.
function verify_Callback(hObject, eventdata, handles)
% hObject handle to verify (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)

load ('np1-20mfcc5st8mix50ms.mat','priornp');

% apply testing testlogliknpVSp(handles.x)=mhmm_logprob(data_nonpain1(handles.x),priornp,transmatnp,munp,Sigmanp,mixmatnp);%NOPAIN MODEL

if testlogliknpVSp(handles.x) < testloglikpVSp(handles.x)
fprintf(' %6.2f %6.2f',testlogliknpVSp(handles.x),testloglikpVSp(handles.x))
set(handles.verification,'String','this cry belongs to no pain class');
else
fprintf(' %6.2f %6.2f',testlogliknpVSp(handles.x),testloglikpVSp(handles.x))
set(handles.verification,'String','this cry belongs to pain class');
end


guidata(hObject,handles)

doesnt matter either pain or not pain wav file(**assuming we know which is pain or not pain audio track), the result sticking with 'this cry belongs to pain class'
