How do I save a series of Output images in a folder (that is inside a for loop)?

folder = 'C:/Jasons images'; % Whatever...
for loopCounter = 1 : whatever...
    filename = fullfile(folder, sprintf('Image %2.2d', loopCounter));
    % Plot to an axes...  Then save to a disk file with exportgraphics():
    exportgraphics(gca, filename);
end

在 MATLAB Online 中打开

for i = 1:251
    imshow(img)
    hold on
    plot([xLeftY, xRightY], [yLeftY, yRightY], 'LineWidth',5,'Color','Yellow');
    plot([xLeftW, xRightW], [yLeftW, yRightW], 'LineWidth',5,'Color','White');
    hold off
    % get figure snap and save to png file
    f = getframe(gcf);
    f = frame2im(f);
    if ~exist('./fd', 'dir')
        mkdir('./fd');
    end
    imwrite(f, sprintf('./fd/%03d.png', i));
end
