I have this code:
miFolder='C:\Users\karina\Documents\MATLAB\11';
if ~isdir(miFolder)
errorMensaje = sprintf('Error: El folder no existe:\n%s', miFolder);
uiwait(warndlg(errorMensaje));
return;
end
filePatron = fullfile(miFolder, '*.jpg');
jpegFil = dir(filePatron);
Resultados='C:\Users\karina\Documents\MATLAB\11\SerieN';
mkdir(Resultados);
for k = 1:10
baseFN = jpegFil(k).name;
fullFN = fullfile(miFolder, baseFN);
I=imread(fullFN);
I2=imcrop(I,[167.5 0.5 660 524]);
imwrite(I2,[Resultados,num2str(k),'.png']);
end
Then what I want is to save the images in the C:\Users\karina\Documents\MATLAB\11\SerieN location but the images of the SerieN are saved in the C:\Users\karina\Documents\MATLAB\11. All the images are saved as SerieN1.png, SerieN2.png and so on, that's ok but I need to those images will be saved in the correct folder. Thank you for your time. Regards.

If you're not going to use fullfile(), and use concatenation like you did, you need to add a trailing space to your folder. It's best to use fullfile() which takes care of all that for you.
baseFileName = sprintf('%d.png', k); % e.g. "1.png"
fullFileName = fullfile(Resultados, baseFileName); % No need to worry about slashes now!
imwrite(I2, fullFileName);

I've just compiled m-files into standalone executables, not DLLs, so I don't think I'm of much help there. Call the Mathworks and ask them. The compiler is very expensive so you might as well get something for your support payment.

For example, if you have video (video.avi) in matlab directory and you want to convert this video into frame sequences and save them in new folder (IMAGESEQUENCES). write this code below:
%%code %%
video = VideoReader('video.avi');
OutVideoDir = 'IMAGESEQUENCES';
mkdir(OutVideoDir);
for i = 1:video.NumberOfFrames
img = read(video,i);
baseFileName = sprintf('%d.png', i); % e.g. "1.png"
fullFileName = fullfile(OutVideoDir, baseFileName);
imwrite(img, fullFileName);
end

Instead of
imwrite(I2,[Resultados,num2str(k),'.png']);
try
imswrite(I2, fullfile(Resultados, ['SerieN', num2str(k), '.png']));
