簡單的來說,國中的 generalizde function 就是Ax=b 。 x=(adjA/detA)b這裏有一個古典伴隨矩陣adjA的觀念, 上面這個解工程書幾乎不引用。 所幸我們能從外文網站找到有關 generalized function The class of all regular sequences of particularly well-behaved functions equivalent to a given regular sequence. A distribution is sometimes also called a "generalized function" or "ideal function." As its name implies, a generalized function is a generalization of the concept of a function. For example, in physics, a baseball being hit by a bat encounters a force from the bat, as a function of time. Since the transfer of momentum from the bat is modeled as taking place at an instant, the force is not actually a function. Instead, it is a multiple of the delta function. The set of distributions contains functions (locally integrable) and Radon measures. Note that the term "distribution" is closely related to statistical distributions. ...e.t.c. ---上面可能是原因。 --問 數學界不給工程書(Ax=b)正確答案的原因﹖ -- ※ Origin: 奇摩 大摩域 <http://bbs.kimo.com.tw/> ◆ From: 59.121.149.188
