bilinear

1. (linear algebra, of a function in two variables) Linear (preserving linear combinations) in each variable.Examples: "The function f(x,y)#61;xy is bilinear, because f(ax#43;bu,y)#61;af(x,y)#43;bf(u,y) and f(x,ay#43;bv)#61;af(x,y)#43;bf(x,v) for all values."not-comparable

2. (complex analysis, physics, engineering) Of or pertaining to a Möbius transformation (type of conformal map representable as the ratio of two linear functions).Examples: "bilinear isotropic hardening"not-comparable
