[edit] Needs more detail

This doesn't explain what the method is, it's pretty much useless, should be stubbed as well.

[edit] Miscategorized

This article doesn't belong under "Analysis". It should be in "Numerical analysis". DavidCBryant 21:34, 21 November 2006 (UTC)

There is no stub category for "Numerical analysis", though. I added it to "Computer graphics stubs" as well, although this is not the only application of bicubic interpolation. The article as it stands is useless anyway, as you have observed. Freederick 23:14, 19 January 2007 (UTC)

[edit] Wrong formula

The article says that

The bicubic interpolation is calculated as follows: 

a00 + a10x + a01y + a20x2 + a11xy + a02y2 + a21x2y + a12xy2 + a22x2y2 + a30x3 + a03y3 + a31x3y + a13xy3 + a32x3y2 + a23x2y3 + a33x3y3

but this is just a general third order function of two variables -- it has nothing to do with bicubic interpolation. Freederick 23:15, 19 January 2007 (UTC)
