Element-wise complex imaginery part operation

Symbolic element-wise complex imaginery part operation for ComplexLazyTensor objects or default element-wise complex imaginery part operation otherwise.

Usage

Im(z)

Arguments

z

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

Value

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

Details

If z is a LazyTensor, see Im.LazyTensor(), else see Im.default().

Examples

if (FALSE) {
# R base operation
Im(1)
Im(1+1i)
# LazyTensor symbolic element-wise complex imaginery part
z <- matrix(2 + 1i^ (-6:5), nrow = 4)         # complex matrix
z_i <- LazyTensor(z, "i", is_complex = TRUE)  # creating ComplexLazyTensor
Im_z <- Im(z_i)                               # symbolic matrix
