Description

Symbolic element-wise square operation for LazyTensor objects.

Usage

# S3 method for LazyTensor
square(x)

Value

An object of class LazyTensor.

Arguments

x

a LazyTensor, a ComplexLazyTensor, a vector of numeric values, or a scalar value.

Details

If x is a LazyTensor, square(x) returns a LazyTensor that encodes, symbolically, the element-wise square of x, i.e. \(x^2\).

Examples

if (FALSE) {
x <- matrix(runif(150 * 3), 150, 3) # arbitrary R matrix, 150 rows, 3 columns
x_i <- LazyTensor(x, index = 'i')   # creating LazyTensor from matrix x, 
                                    # indexed by 'i'
Square_x <- square(x_i)             # symbolic matrix, 150 rows and 3 columns
