对p= 2,这称为弗罗贝尼乌斯范数(Frobenius norm)或希尔伯特-施密特范数(Hilbert–Schmidt norm),不过后面这个术语通常只用于希尔伯特空间。这个范数可用不同的方式定义: 这里A* 表示A的共轭转置,σiσ�σi��是A的奇异值,并使用了迹函数。弗罗贝尼乌斯范数与K^{n}}K^{n}}上欧几里得范数非常类似,来自所有...

In mathematics, a matrix norm is a natural extension of the notion of a vector norm to matrices. In what follows, K will denote the field of real or complex numbers. Let K^{m times n} denote the vector space containing all matrices with m rows and n columns with entries in K. ...
