How can I plot or place three or four figures in one figure

I have three figures size 198kb, 208kb and 187kb. How can i make those figures showing in a single panel? say the figure names are EM_SH_01, EM_SH_02,EM_SH_03

If I understood correctly, what you could do is use subplots. You could get your 4 images and then export them as one panel

myimage = imread('image1.jpg');
myimage2 = imread('image2.jpg');
myimage3 = imread('image3.jpg');
myimage4 = imread('image4.jpg');

subplot(2,2,1)
image("myimage")
title('EM_SH_01')

subplot(2,2,2)
image("myimage2")
title('EM_SH_02')

subplot(2,2,3)
image("myimage3")
title('EM_SH_03')

subplot(2,2,4)
image("myimage4")
title('EM_SH_04')

I tried subplot. But there's a gap sustain between the images. If I could use montage, I think the problem could have been resolved. But my images are of different sizes.

[Keegan Carvalho]

Try resizing the image using imresize().

Regarding the gaps between subplots, I came across this link some time ago.

I could not understand it how to use. Better if you can help me writing the code using this function according to my problem

[Image Analyst]

Show your code for using montage() or imtile().

[Joydeb Saha]

imgNames = dir('*.jpg') ;   % give your exntenion of images in the folder 
N = length(imgNames) ;      % toal number of images 
thepath = 'E:\New Rev\figs';  % give path of the folder here 
% loop for each image
for i = 1:N
    thisImg = imgNames(i).name ; 
    I=imread(thisImg);
    figure(1)
    imshow(I) ;
    L = imresize(I,.50,'bilinear');    
    figure(2)
    imshow(L);
    % WRite image into a folder 
    [filepath,name,ext] = fileparts(thisImg) ; 
    name = [thepath,filesep,name,'.jpg'] ;
    imwrite(L,name)
end

out = montage('EM_SH1.jpg','EM_SH2.jpg','EM_SH3.jpg','EM_SH4.jpg');

The problem is that if resize it to 0.50, the actual size in kb remains different

[Image Analyst]

Why are you resizing? Just call montage on the original files. If you need to resize the output, call imresize() on "out". Then call

imshow(out);

[Joydeb Saha]

uint8, double, uint16, logical, single, int16

Instead its type was char.

Error in montage>parse_inputs (line 246)

validateattributes(varargin{1}, ...

Error in montage (line 114)

[I,cmap,mSize,indices,displayRange,parent] = parse_inputs(varargin{:});

getting this error if i use montage

[Joydeb Saha]

myimage1 = imread('EM_SH1.jpg');
myimage2 = imread('EM_SH2.jpg');
myimage3 = imread('EM_SH3.jpg');
myimage4 = imread('EM_SH4.jpg');

% out = montage('ElNino_SH_1516DJF.jpg','ElNino_SH_8283DJF.jpg','ElNino_SH_9192DJF.jpg','El Nino_Anomaly_1997_98.jpg');
out = montage('myimage1','myimage2','myimage3','myimage4');

imshow(out);

size of the images are: 197kb, 208kb,191kb,194kb

the error I am geeting is:

uint8, double, uint16, logical, single, int16

Instead its type was char.

Error in montage>parse_inputs (line 246)

validateattributes(varargin{1}, ...

Error in montage (line 114)
