MATLAB: How to extract high resolution from a low resolution image

low resolution to high resolution

If I read a image taken from 13 MP mobile camera then is it possible to add additional pixels in order to obtain high resolution image. Please provide me the MATLAB code.

This is a subjective topic, imresize increase the size of the images, as already said by @KSSV Sir you can proceed that. The resolutions depend on the number of spatial coordinates (PPI) and bit length per pixel.
higher_image=imresize(input_image,scaling_factor)
What you exactly want? Spatial resolution?
For specific, you can look at interpolation too. Please note that by this approach you can increase the number of pixels only, it doesn't increase the actual information of the real image.
