nk::Value
Core MATLAB-compatible multidimensional array and scalar value type.

nk::comm::quantiz_indx
Value quantiz_indx(const Value &sig, const Value &partition, std::pmr::memory_resource *mr=nullptr)
One-output form of quantiz — bin index per sample (indx = quantiz(sig, partition)).
nk::comm::quantiz
QuantizResult quantiz(const Value &sig, const Value &partition, const Value &codebook, std::pmr::memory_resource *mr=nullptr)
Three-output form of quantiz ([indx, quantv, distor] = quantiz(sig, partition, codebook)).
nk::comm::QuantizResult
Result of the three-output form of quantiz.
Definition quantiz.hpp:33
nk::comm::QuantizResult::distor
double distor
mean((sig - quantv)^2).
Definition quantiz.hpp:36
nk::comm::QuantizResult::indx
Value indx
Bin index per sample.
Definition quantiz.hpp:34
nk::comm::QuantizResult::quantv
Value quantv
codebook(indx + 1).
