conj!
conj!(A)
Convert an array to its complex conjugate in-place
Examples
-
Convert an array to its complex conjugate:
julia> A = [1+2im, 3-4im, 5+6im]; julia> conj!(A) 3-element Array{Complex{Int64},1}: 1 - 2im 3 + 4im 5 - 6imThis example converts the array
Ato its complex conjugate in-place. The imaginary parts of each element are multiplied by -1. - Modify a matrix of complex numbers:
julia> M = [1+2im 3-4im; 5+6im 7-8im]; julia> conj!(M) 2×2 Array{Complex{Int64},2}: 1 - 2im 3 + 4im 5 - 6im 7 + 8imIt converts each element of the matrix
Mto its complex conjugate.
Common mistake example:
julia> B = [1 2; 3 4];
julia> conj!(B)
ERROR: MethodError: no method matching conj!(::Array{Int64,2})In this example, the function conj! is called on a non-complex array. The conj! function is specifically designed for complex arrays, so ensure that the input array contains complex numbers before using conj!.
