Detailed Description

Return the vector of coefficients of the polynomial resulting from the \(k\)th-order differentiation of a univariate polynomial of arbitrary degree.

See the documentation of pm_polynomial for details of the implementation.

Parameters
[out]diff: The output contiguous vector of the same type and kind as the input coef, of size size(coef) - order, containing the coefficients (in the order of increasing power) of the resulting polynomial from the \(k\)th-order differentiation of the input polynomial with coefficients coef of arbitrary degree.
By definition, the degree of the diff polynomial is size(diff) - order.
[in]coef: 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 (in the order of increasing power) of the univariate polynomial whose \(k\)th-order derivative must be returned.
By definition, the degree of the coef polynomial is size(coef) - 1.
This means that the condition coef(size(coef)) /= 0. is expected to hold (although not enforced).
[in]order: The input scalar nonnegative integer of default kind IK containing the order of the derivative to compute.
(optional, default = 1)

Warning
The condition 0 <= order must hold for the corresponding input arguments.
The condition size(diff) == max(1, size(coef) - order) 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.
