Amplify?? you mean resize? if that's what you mean here is the code

IResized= imresize(I,scale,'nearest');

OK, that's fine. I agree with everything you said. I've never heard of "C0 Interpolation" but if that's standard terminology in some sub-field of image processing, that's fine.

Actually I made a mistake it is C-1. It is one order lower than the polynomial being used. It means continuity. C0 means the curves touches at the boundary( Which in nearest neighbor clearly doesn't). C1 means the first derivative is also continuous and so on.

Go down to parametric continuity.
