Broadcasted Complex Numeric Operations
Description
The bc.cplx() function performs broadcasted complex numeric operations on pairs of arrays.
Note that bc.cplx() uses more strict NA checks than base ‘R’:
If for an element of either x or y, either the real or imaginary part is NA or NaN, than the result of the operation for that element is necessarily NA.
Usage
bc.cplx(x, y, op, ...)
## S4 method for signature 'ANY'
bc.cplx(x, y, op)
Arguments
x, y
|
conformable vectors/arrays of type complex.
|
op
|
a single string, giving the operator. Supported arithmetic operators: +, -, *, /. Supported relational operators: ==, !=. |
…
|
further arguments passed to or from methods. |
Value
For arithmetic operators:
A complex array as a result of the broadcasted arithmetic operation.
For relational operators:
A logical array as a result of the broadcasted relational comparison.
