这种类型的问题反复的出现,应该进行详细的回答,而不是回答”Matlab使用个高度优化的库”或者“Matlab使用了MKL”。 History: Matrix multiplication (together with Matrix-vector, vector-vector multiplication and many of the matrix decompositions) is (are) the most important problems in linear algrebra. Enginee...
Many mathematical operations can be applied to matrices and vectors in Matlab such as addition, subtraction, multiplication, and division of matrices, etc. Matrix or Vector Multiplication If $x$ and $y$ are both column vectors, then $x’*y$ is their inner (or dot) product, and $x*y’$...
The prices matrix is5-by-3, the quantity matrix (vector) is3-by-1, so the resulting matrix (vector) is5-by-1. Multiplying Two Matrices Matrix multiplication also follows the rules of matrix algebra. In matrix algebra notation, ifAis anm-by-nmatrix andBis ann-by-pmatrix A=⎡⎢⎢...

The multiplication of a vector by a matrix is the kernel operation in many algorithms used in scientific computation. This paper outlines four parallel matrix – vector multiplication implementations on a cluster of workstations. These parallel implementations are based on the dynamic master – worker...

EXAMPLE 1: Implementing fft() in operator form. As is well-known, the operation fft(x) can be represented as a matrix-vector multiplication. If you have the Signal Processing Toolbox, the relevant matrix can be generated using the DFTMTX function. Otherwise, it can be generated as follows...
