bilinear

Linear both ways

Bilinear describes a mathematical function or operation that is linear in each of two variables when the other is held constant.

The term appears in algebra, geometry, and computer graphics, where bilinear interpolation smooths pixel values by averaging neighboring points: The image was resized using bilinear filtering.
