Element-wise square (power-2) operation

Symbolic element-wise square operation for LazyTensor objects or standard element-wise square operation otherwise, i.e. \(x^2\).

Usage

square(x)

Arguments

x

input for square.default() or square.LazyTensor().

Value

See value of square.default() or square.LazyTensor()

Details

If x is a LazyTensor, see square.LazyTensor(), else see square.default().

See also

square.default(), square.LazyTensor()

Examples

if (FALSE) {
# Numerical input
square(4)
square(1:4)
# LazyTensor symbolic element-wise square
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
