Read about imresize. This is the function you want.

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

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.

MATLAB: Kriging codes in matlab

Walter's answer links to the best toolbox that I know of for kriging in Matlab. However, if you really want to use the gstat method, I would suggest actually using gstat itself (in R). The R package is much more robust than anything you're going to find in Matlab (and I say that as a person with a strong preference for Matlab over R in almost all other contexts).

Also consider whether kriging (or any geostatistical interpolation method) is really ideal for your dataset. I see a lot of people trying to use kriging simply because that's the ArcGIS default, and they want to create a similar map, without taking the time to understand the many assumptions used to generate those maps.
