how not to display everything

Hi,

Every time I run the following code it displays lot of extra ouputs. I just need it to display the Aic values at the end.

Can someone please help me ?

much Thanks.

Code:

clc;
clear;

T = 300;

a0  = 0.1; a1 = 0.4; a2 = 0.0; b1 = 0.2; b2= 0.0;  % garch parameters

epsi  = randn(T+2000,1);           
ut   = zeros(T+2000,1);          % garch data
sig2 = zeros(T+2000,1);          % sigma squared in garch model

unvar = a0/(1-a1-a2-b1-b2); % unvar is the unconditional variance.. initial condition

for i = 1:T+2000
                 if i==1 
                     sig2(i) = a0 + a1*unvar + a2*unvar + b1*unvar + b2*unvar;
                     sig =(sig2(i))^0.5;
                     ut(i) = epsi(i) * sig;                 
                 elseif i==2
                     sig2(i) = a0 + a1*(ut(1))^2 + a2*unvar + b1*sig2(1)+ b2*unvar;
                     sig =(sig2(i))^0.5;
                     ut(i) = epsi(i) * sig; 
                 else
                     sig2(i) = a0 + a1*(ut(i-1))^2 + a2*(ut(i-2))^2 + b1*(sig2(i-1)) + b2*(sig2(i-2));
                     sig=(sig2(i))^0.5;
                     ut(i) = epsi(i) * sig;
                 end
end

utl = ut(2001:T+2000);

Mdl1 = garch('Offset',NaN,'GARCHLags',1,'ARCHLags',1);
[EstMdl1,EstParamCov1,logL(1)] = estimate(Mdl1,utl);
numParams(1) = sum(any(EstParamCov1));

Mdl2 = garch(5,5);
[EstMdl1,EstParamCov2,logL(2)] = estimate(Mdl2,utl);
numParams(2) = sum(any(EstParamCov2));

numObsv = length(utl);
[AIC1] = aicbic(logL(1), numParams(1))
[AIC2] = aicbic(logL(2), numParams(2))

Here, study this function to see how I turn off warnings. The instructions for other warnings that you may encounter that are not turned off by my function are in the comments.

% Suppress warnings.
function TurnOffWarnings()
  try
    % To set the warning state, you must first know the message identifier for the one warning you want to enable. 
    % Query the last warning to acquire the identifier.  For example: 
    % warnStruct = warning('query', 'last')
    % messageID = warnStruct.identifier
    % messageID =
    %    MATLAB:concatenation:integerInteraction
    
    % Turn off this warning "Warning: Image is too big to fit on screen; displaying at 33% "
    warning('off', 'Images:initSize:adjustingMag');
    
    % Get rid of warning about roipolyold being deprecated: 
    % "Warning: Function ROIPOLYOLD will be removed in the future. Use ROIPOLY instead"
    warning('off', 'images:removing:function');
    
    % Get rid of warning about directory already existing: 
    % "Warning: Directory already exists."
    warning('off', 'MATLAB:MKDIR:DirectoryExists');

    % Turn off note "Warning: Added specified worksheet." that appears in the command window.
    warning('off', 'MATLAB:xlswrite:AddSheet');
  catch ME
    errorMessage = sprintf('Error in function %s() at line %d.\nDo you have the file already open in Excel?\nPlease check that the file is not open anywhere.\n\nError Message:\n%s', ...
      ME.stack(1).name, ME.stack(1).line, ME.message);
    fprintf(1, '%s\n', errorMessage);
    WarnUser(errorMessage);
  end
  return; % from TurnOffWarnings

Thanks I could prevent warnings from being displayed by using warning off command.

However, my biggest problem is preventing the following part from displaying.

Part that i want not to be displayed:
