| progr. | function rank | ранг функции (functions that operate on data may be classified by the number of dimensions they act on. Ordinary multiplication, for example, is a scalar ranked function because it operates on zero-dimensional data (individual numbers). The cross product operation is an example of a vector rank function because it operates on vectors, not scalars. Matrix multiplication is an example of a 2-rank function, because it operates on 2-dimensional objects (matrices) Alex_Odeychuk) |
| progr. | 2-rank function | функция 2-го ранга (operates on 2-dimensional objects (matrices) Alex_Odeychuk) |
| math. | rank function | функция ранга |
| Makarov. | second-rank time correlation function | функция временной корреляции второй степени |
| progr. | vector rank function | функция векторного ранга (operates on vectors, not scalars Alex_Odeychuk) |
