Element-wise complex real part operation

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

Usage

Re(z)

Arguments

z

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

Value

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

Details

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

Examples

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