How to export the data corresponding to the new pixel size?

Hi,
I have image data with 100*100 (pixel x pixel) and the pixel size is 10. Each pixel has a resulted value e.g., temperature
Now I would like to change the pixel size to 5 and still keep the same size of the image.
I wonder how to get the new image data (X, Y, and temperature) corresponding to the pixel size 5.
I really appreciate your help.
Thanks

Then you don't actually have an image, but gridded (or scattered) X,Y,Z data. You can either interpolate with the normal interpolation tools, or convert your coordinates to a grid of integer positions and use that to fill a matrix so you can use imresize.
