Hi there, I wanted to know if someone could explain to me how are image matrices (given to be of lower resolution) "merged/combined" to create another of greater size (thus resolution as well). For instance, if I have 4 matrices that are 144x144 and from these I would like to get a 576x576 image. I tried doing puffing 2 matrices together, but this only worked for me in a horizontal direction and not vertically. Therefore, when I tried a 3rd matrix, the resulting matrix was just getting larger on the horizontal, but not on the vertical direction, causing my image to just look weird.

There may be a function for this, so I am looking but I would appreciated some guidance,

Thank you,

Bc
