'Matrix Interpolation using ML technique

I am currently having a matrix of input size -> (512 X 7)with values in it. I would like to interpolate to twice its size i.e. the output size is -> 1024 X 14 using any Machine Learning technique.

I am currently stuck with it as there are no features or labels associated with it. I have read some papers which employ Random Forest for this, but they all have features in their case. Can anyone guide me as to how I may approach this ?
