ok ImageAnalyst. Apart from course instructor, what creative things can be done using MATLAB. I have seen some codings like indian flag, heart beating, man and hen fight... Is there any possibility to develop any handheld electronic game devices, which can use any MATLAB application.. it is not mandatory to install matlab software in that system...

i had a discussion with a programmer who works with google. he works with identification of spam mails. I asked is it possible to use MATLAB to identify spam... I would be happy if you explain this concept.

MATLAB is Turing Complete. You can program anything that does not require special hardware.

Some languages are better suited for some tasks than for others.

在 MATLAB Online 中打开

imagedata = imread('YourImage.jpg');
imwrite(imagedata, 'YourNewImage.tif');  %can even change the image type

imread can give values like [156 176 187...]..... does the same image is regenerated if i try imwrite([156 176 187...]...

imwrite(uint8([156 176 187...]...)

If you used [156 176 187...] then the data class would be "double" (because that is the default for MATLAB), and that would be a problem, as MATLAB assumes that "double" values should have a range of 0 to 1 for images.
