Description

Simple wrapper returning an instance of LazyTensor indexed by "i". Equivalent to LazyTensor(x, index = "i").

Vi(x, is_complex = FALSE)

Value

An object of class "LazyTensor" indexed by "i". See ?LazyTensor for more details.

Arguments

x

A matrix of numeric values, or a scalar value.
