Element-wise inverse operation.

Symbolic element-wise inverse operation for LazyTensor objects or standard element-wise inverse operation otherwise, i.e. 1/x.

Usage

inv(x)

Arguments

x

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

Value

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

Details

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

See also

inv.default(), inv.LazyTensor()

Examples

if (FALSE) {
# Numerical input
inv(4)
inv(1:10)
# LazyTensor symbolic element-wise inverse
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'
Inv_x <- inv(x_i)                   # symbolic matrix, 150 rows and 3 columns
