Interpolate

[mtazzari]

To generalize interpolate to nx, ny matrix :

1. change nx -> ny in interpolate_core because of the row-wise computation of base
2. to call interpolate_h and interpolate_d with the correct ny, we must add ny to the inputs of all the functions that take the data matrix, e.g. galario_sample etc.

I have already tried to implement 1. just to run test_galario and it seems to work fine. This must be propagated with 2.

I rewrote interpolate_core to be more readable and added the matching equations. I also maded it work for our data format. Interesting that only ny, not nx is needed as an argument. I guess the row index is implicit in indu. To really make it work for a nonsquare matrix. indv has to use a dv such that dv != du is allowed. Currently it's not possible.

But with these fixes, the tests don't pass anymore

I fixed this in 039b42f.
