I want to get multiple jpg files by path and name through the function uigetfile and display them in the picture window.

[file, path]= uigetfile(('*.jpg',...
    'Select One or More Files', ...
    'MultiSelect', 'on');

Hi KiBaek.

It is my understanding that you want to select multiple jpg images and display them in multiple figure windows or same figure window. Here’s a sample code for that:

Code to display in multiple figure windows:

[fileNames, filePath] = uigetfile('*.jpg', 'Select JPG files', 'MultiSelect', 'on');
% Check if the selected files are returned as a cell array
if iscell(fileNames)
    numFiles = numel(fileNames);
else
    numFiles = 1;
    fileNames = {fileNames};
end
for i = 1:numFiles
    % Construct the full file path
    fullFilePath = fullfile(filePath, fileNames{i});

    % Read and display the image
    image = imread(fullFilePath);
    figure;
    imshow(image);
    title(fileNames{i});
end

Code to display in same figure window:

[fileNames, filePath] = uigetfile('*.jpg', 'Select JPG files', 'MultiSelect', 'on');

% Check if the selected files are returned as a cell array
if iscell(fileNames)
    numFiles = numel(fileNames);
else
    numFiles = 1;
    fileNames = {fileNames};
end

% Calculate the number of rows and columns for the subplot
numRows = ceil(sqrt(numFiles));
numCols = ceil(numFiles / numRows);

figure;

for i = 1:numFiles
    % Construct the full file path
    fullFilePath = fullfile(filePath, fileNames{i});
    image = imread(fullFilePath);
    subplot(numRows, numCols, i);
    imshow(image);
    
    % Set the title of the subplot to the corresponding file name
    title(fileNames{i});
end    

You can refer to the following documentation to know more about the functions used:
