Functions
Value	nk::signal::nextpow2 (double n, std::pmr::memory_resource *mr=nullptr)
	Smallest integer p such that \( 2^p \ge n \) (scalar form).
Value	nk::signal::nextpow2 (const Value &x, std::pmr::memory_resource *mr=nullptr)
	Vectorised nextpow2 — applies elementwise to an array.
Value	nk::signal::fftshift (const Value &x, std::pmr::memory_resource *mr=nullptr)
	DC-to-center reordering for FFT output (multidim form).
Value	nk::signal::ifftshift (const Value &x, std::pmr::memory_resource *mr=nullptr)
	Inverse of fftshift — shift by floor(extent/2).
Value	nk::signal::fftshift (const Value &x, int dim, std::pmr::memory_resource *mr=nullptr)
	Single-dim fftshift — shift only along axis dim.
Value	nk::signal::ifftshift (const Value &x, int dim, std::pmr::memory_resource *mr=nullptr)
	Single-dim ifftshift — inverse of single-dim fftshift.
