### Target language

Translate to Korean (한국어).

Language code: ko.

### Grammar and tone

1) Use polite, instructional Korean (e.g. 합니다/하세요 style).
2) Keep the tone consistent with the existing Korean FastAPI docs.

### Headings

1) Follow existing Korean heading style (short, action-oriented headings like “확인하기”).
2) Do not add trailing punctuation to headings.

### Quotes

   * #transform} methods all return {@link Double#NaN}. The {@link #inverse} method returns the same
   * instance.

  public static LinearTransformation forNaN() {
    return NaNLinearTransformation.INSTANCE;
  }

  /** Returns whether this is a vertical transformation. */
  public abstract boolean isVertical();
