You can change the image matrix size with imresize(). This does not change the actual real world spatial resolution (like how well you can resolve to points close together in the scene), just the number of pixels. To increase the resolution you need to use a spatial filter, like deconvlucy() or wiener2() which require you to supply a point spread function and a noise spectrum.

You could look into techniques for super resolution. This is an entire field of research that uses multiple low resolution images to create high resolution images.

Thanks For Your Answer . I read some Algorithm but that was out of my mind. Do u Know some Simple Algorithm or some links where i can find in simple Language....
The Drizzle algorithm is pretty straightforward. See
