示例1: if
void Householder<T>::mulLeft(NDArray<T>& matrix, const NDArray<T>& tail, const T coeff) {
// if(matrix.rankOf() != 2)
// throw "ops::helpers::Householder::mulLeft method: input array must be 2D matrix !";
if(matrix.sizeAt(0) == 1)
matrix *= (T)1. - coeff;
else if(coeff != (T)0.) {
NDArray<T>* bottomPart = matrix.subarray({{1, matrix.sizeAt(0)}, {}});
NDArray<T> bottomPartCopy = *bottomPart;
