Return the vector of coefficients of the polynomial resulting from the addition of a polynomial to another polynomial of arbitrary degrees.

Return the vector of coefficients of the polynomial resulting from the addition of a polynomial to another polynomial of arbitrary degrees.
See the documentation of pm_polynomial for details of the implementation.
- Parameters
-
[out] | add | : The output contiguous vector of the same type and kind as the input lhs , of size max(size(lhs), size(rhs)) , containing the coefficients (in the order of increasing power) of the resulting polynomial from the addition of the polynomial lhs of arbitrary degree to another polynomial rhs of arbitrary degree.
By definition, the degree of the add polynomial is size(add) - 1 .
|
[in] | lhs | : The input contiguous vector of non-zero size of,
-
type
complex of kind any supported by the processor (e.g., CK, CK32, CK64, or CK128), or
-
type
real of kind any supported by the processor (e.g., RK, RK32, RK64, or RK128),
containing the coefficients of the left-hand-side polynomial in the addition, in the order of increasing power.
By definition, the degree of the lhs polynomial is size(lhs) - 1 .
This means that the condition lhs(size(lhs)) /= 0. must hold.
|
[in] | rhs | : The input contiguous vector of non-zero size of the same type and kind as lhs , containing the coefficients of the right-hand-side polynomial in the addition, in the order of increasing power.
By definition, the degree of the rhs polynomial is size(rhs) - 1 .
This means that the condition rhs(size(rhs)) /= 0. must hold.

- Warning
- The condition
0 < size(rhs)
must hold for the corresponding input arguments.
The condition 0 < size(lhs)
must hold for the corresponding input arguments.
The condition size(add) == max(size(lhs), size(rhs))
must hold for the corresponding input arguments.
The condition lhs(size(lhs)) /= 0.
must hold for the corresponding input arguments.
The condition rhs(size(rhs)) /= 0.
must hold for the corresponding input arguments.
These conditions are verified only if the library is built with the preprocessor macro CHECK_ENABLED=1
.

The
pure
procedure(s) documented herein become impure
when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1
.
By default, these procedures are pure
in release
build and impure
in debug
and testing
builds.
