atan: Element-wise arc-tangent operation.

Description

Symbolic element-wise arc-tangent operation for LazyTensor objects or standard element-wise arc-tangent operation otherwise.

Usage

atan(x)

Value

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

Arguments

x

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

Author

Chloe Serre-Combe, Amelie Vernay

Details

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

atan.default(), atan.LazyTensor()

Examples

if (FALSE) {
# R base operation
atan(0)
atan(-1)
# LazyTensor symbolic element-wise arc-tangent
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'
Atan_x <- atan(x_i)                 # symbolic matrix, 150 rows and 3 columns
