Here we present a hyperparallel quantum algorithm for matrix multiplication with time complexityO(N2), which is better than the best known classical algorithm. In our scheme, anNdimensional vector is mapped to the state of a single source, which is separated toNpaths. With the assistance of ...
If not, we can use a gradient vector formula to refine the guessed X and perform another iteration of A×X+Y using the refined X. The most time-consuming part of such an iterative approach is in the evaluation of A×X+Y, which is a sparse matrix–vector multiplication and accumulation....
I'm writing to ask about the time complexity of the sparse-sparse matrix multiplication implemented in this library. Suppose the sizes of the two sparse matrices aren×nand the numbers of non-zero elements in them are bothm. Best wishes. ...
Matrix-vector multiplication The methods for photonic matrix-vector multiplications (MVMs) mainly fall into three categories: the plane light conversion (PLC) method, Mach–Zehnder interferometer (MZI) method and wavelength division multiplexing (WDM) method. The detailed mechanism of these MVMs can be...
Making use of the internal structure of the matrix M[i], the time complexity of solving the eigenvalue problem stated in Eq. (20)—required to update one local tensor of the MPS—is O(D3). This scaling results largely from the the matrix-vector multipli- cations involved in the ...

cuBLAS 12.0 extends the cuBLAS API to support 64-bit integer problem sizes, leading dimensions, and vector increments. These new functions have the same API as their 32-bit integer counterparts except that they have a_64suffix in the name and declare the corresponding parameters asint64_t. ...

First of all, matrix multiplication can be thought of as a sequence of vector–matrix multiplications: (8.8)An×m⋅Bm×l:=(a1T⋅Ba2T⋅B⋮anT⋅B), where aiT is the ith row of A, and aiT ⋅ B is a vector–matrix multiplication. Note that fB(aiT):=aiT ⋅ B is a linea...
