Element-wise power operation

Symbolic element-wise power binary operation for LazyTensor objects or default element-wise power operation otherwise, i.e. \(x^y\).

Usage

x^y

Arguments

x, y

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

Value

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

Details

If x or y is a LazyTensor, see ^.LazyTensor(), else see ^.default().

See also

^.default(), ^.LazyTensor()

Examples

if (FALSE) {
# R base operation
3^2
(1:10)^3
2^(1:10)
(1:10)^(1:2)
# LazyTensor symbolic power operation
x <- matrix(runif(150 * 3), 150, 3) # arbitrary R matrix, 150 rows, 3 columns
y <- matrix(runif(250 * 3), 250, 3) # arbitrary R matrix, 250 rows, 3 columns
x_i <- LazyTensor(x, index = 'i')   # creating LazyTensor from matrix x, 
                                    # indexed by 'i'
y_j <- LazyTensor(y, index = 'j')   # creating LazyTensor from matrix y, 
                                    # indexed by 'j'
x_pow_y <- x_i^y_j                  # symbolic matrix
