findMerges()

MergeArray GSFUtils::findMerges	(	const Component1DArray &	componentsIn,
		const int8_t	reducedSize
	)

Find the order in which the components need to be merged.

Returns an MergeArray with the merges (To,From). The index of the merged From is always smaller than the To (RHS is smaller than LHS)

Component1DArray : Array of simplified 1D components used to calculate the merge order using q/p. Its size can not exceed GSFConstants::maxComponentsAfterConvolution

reducedSize The size we want to reduce the mixture to. Needs to be smaller than the numComponents of the componentsIn array

  const int32_t n = componentsIn.numComponents;
  if (n < 0 || n > GSFConstants::maxComponentsAfterConvolution ||
      reducedSize > n) {
    throw std::runtime_error("findMerges :Invalid InputSize or reducedSize");
  }
  return findMergesImpl(componentsIn, n, reducedSize);
