This comment is a little bit confuse since the name of the parameter already change to columnMajor, we can use a bool value to tell the readers the output is columnMajor or rowMajor.
ex :
```
bool columnMajor = true;
CustomImputation<double> imputer(customValue);
imputer.Impute(input, outputT, mappedValue, 0/*dimension*/, columnMajor );
```
