Hi, everyone!
I have a database of images (the number of images may vary) with different dimensions, need to change thier width/high (resize whole image but not crop it) to same one, then save the new images in a separate folder.
I have tried the im.resize function, but the image is cropped and information lost. It is necessary that the integrity of the image does not change, but only its parameters.

Have done this:
for k = 1:9
% Create an image filename, and read it in to a variable called imageData.
jpgFileName = strcat('book-0', num2str(k), '.jpg');
if exist(jpgFileName, 'file')
imageData = imread(jpgFileName);
resize = imresize(imageData,[100 150]);
imwrite (resize,'resize.jpg');
fprintf('File %s does not exist.\n', jpgFileName);
how can I save them one by one?

outfilename = strcat('resize_', jpgFileName);
imrewrite(resize, outfilename);
