Description

simple versions: Z_i = Y_i - X_i
expanded versions: Z_i = Y_i - (A*X_i+B)
The complex floating-point versions exist in two variants: in the first variant (e.g., VCF_subrV, VCFx_subrV), X, Y, and Z are all complex; in the second variant, Y is real-valued (e.g., VCF_subrReV - "reverse subtraction of a real vector", i.e., subtraction of a complex vector from a real vector).

Error handling

floating-point versions: none;
integer versions: see chapter 5.2.

Return value

none
