For a matrix Bm×l, and a m-vector u, uT ⋄ B is defined as: (8.11)uT⋄B:=(uT⋄b1,uT⋄b2,…,uT⋄b1), where bi denotes the ith column of B. Thus uT ⋄ B is an m × l matrix. For example: (8.12)(5,2)⋄(2314):=((5,2)⋄(2,1)T,(5,2)⋄(3,4)...

We present the design of a planar-integrated optoelectronic vector-matrix multiplier. 我们目前的设计,平面集成光电子矢量矩阵乘法。 www.syyxw.com 2. Using FMM algorithm, although the iterative process dramatically accelerated by calculation, vector matrix is greatly reduced storage. 采用FMM算法,虽然大大...
To span more rows and fewer columns, change COLUMNS(TheRow)/2 to COLUMNS(TheRow)/N where N is the number of rows in the resulting matrix. A screen shot of the data and resulting matrices is shown below: For formulas that do the reverse of these functions, namely create a vector (row...
