image_folder ='E:\Resize Image'
filenames = dir (fullfile(image_folder,'*.jpeg'))
total_images = numel(filenames);
results=[];
for n= 1:total_images;
f= fullfile(image_folder, filenames(n).name);
disp(f);
our_images= imread (f);
% CONTRAST STRECHING
s = imadjust (our_images,stretchlim(our_images,[0.01 0.99]),[]); %menentukan nilai maksimum dan minimum untuk peregangan
% FILTERING
noise = imnoise (s,'gaussian',0.05);
denoise = medfilt2(noise);denoise1 = imgausstfilt (noise, 2) ;

Ran in:
Try imgaussfilt instead of imgausstfilt (note the extra t)
denoise1 = imgaussfilt(randn(100),2); % works
denoise1 = imgausstfilt(randn(100),2); % error
Unrecognized function or variable 'imgausstfilt'.
