(of a function or functor) changing in the opposite way to the way in which the variable or object changes..
Using contravariant: Examples
Take a moment to familiarize yourself with how "contravariant" can be used in various situations through the following examples!
Example
In mathematics, a contravariant functor is a functor that reverses morphisms and preserves their composition.
Example
The contravariant behavior of the tensor is responsible for the fact that it transforms as a covector.
Example
The contravariant components of a vector transform differently than the covariant components under a change of basis.
Summary: contravariant in Brief
The term 'contravariant' [ˌkɒntrəˈveəriənt] refers to a function or functor that changes in the opposite way to the way in which the variable or object changes. It is commonly used in mathematics to describe the behavior of tensors and vectors under a change of basis.
