vector multiply (SpMV), y ← y + A · x, where A is a symmetric, sparse matrix (i.e., A = A T ) and x,y are dense column vectors called the source and destination. We also consider the generalization of SpMV to multiple vectors ...
Here you can perform matrix multiplication with complex numbers online for free. However matrices can be not only two-dimensional, but also one-dimensional (vectors), so that you can multiply vectors, vector by matrix and vice versa.After calculation you can multiply the result by another matrix...

In this example, a first data set (the matrix) and a second data set (the vector) are distributed across multiple processing nodes. Performance of the overall multiplication operation may require communication of data among the processing nodes. In various embodiments, fine-grained communication of...
Specifically, the number of floating point operations in y = Ax + y is always twice the number of nonzeros in A (one multiply and one add per element), independent of the matrix dimensions. In contrast, the more general form also includes the influence of the vector operation βy, ...

Each operations(+, multiply) has roughly the same cost reading/writing variables is “free” 但是现实情况下,变量们都是一个个在内存中的字节。 并且编译器将控制指令翻译成低级指令;硬件执行这些指令; 有些运算操作有比较相近的时钟周期,但是读和写操作成本是运算操作成本的 100 倍左右。
