sum of two vectors 中文意思是什麼
sum of two vectors
解釋
二向量和-
Any two vectors whose vector sum equals a given vector are called the components of that vector.
假如任意兩個矢量的和等於一個給定的矢量，這兩個矢量就稱為該給定矢量的分量。 -
In the third section we firstly introduce the concept of frame vector for a unitary system, then give a if - and - only - if condition for it and at last we get the condition for the sum a 1 + b 2 to be a frame vector, where a, b are two operators and 1, 2 are two frame vectors
第三節先引入酉系統的框架向量的概念，然後給出一個酉系統中框架向量的充要條件，最後得出兩個框架向量_ 1與_ 2 ，分別經過兩個運算元a ， b作用后，它們的和a _ 1 + b _ 2在什麼情況下仍是框架向量。
