write data to table (interpolated)

[bfeddeck]

I need a way to add 2D data to a table between cells. Similar to interpolated but backwards.
For example: I have a 2D table and the value 2.5 needs to be distributed between 4 cells in the correct proportions. Maybe 2.25 in cell 0,0, 2.75 in cell 0,1, and so on.

Why not just use insert into array and the index where you need it to be inserted.

It seems to me you want to do something like antialiasing, where you want to add a point into a 2D integer lattice, but the point has fractional coordinates. Thus you want to fill 4 adjacent cells proportionally such that the "center of gravity" of the four cells is located at the fractional indices. Is this correct?

I have a 1D version that fills two adjacent cells in a histogram according to the fractional index. Should be easy to adapt it to 2D. 🙂

That is exactly what I want to do.
Can I get your 1D version?

Here's a simple demo that uses my 1D version (LabVIEW 7.0) ;).

I would of thought you could do it with a 2D array but Christian probably has a better idea.
