Matrix interpolation in R

Question

I have two matrices with dimensions 96x97 and 180x360. I need to find a correlation between them, but for this, they must have the same dimension. Therefore, I want to interpolate a 96x97 matrix and get a 180x360 matrix. With what function can this be done? Help me, please.

Answer 1

The following packages provide a variety of matrix interpolator functions. Pick one according to the quality vs. time vs. difficulty of use you like.

All available at CRAN. Probably some more I have forgotten about.
