Suppose you have to evaluate an expression like A*B*C*D*E where A,B,C,D and E are matrices. Since matrix multiplication is associative, the order in which multiplications are performed is arbitrary. However, the number of elementary multiplications needed strongly depends on the evaluation orde...

The input consists of several tests. For each tests: The first line contains n (1≤n≤800). Each of the following n lines contain n integers -- the description of the matrix A. The j-th integer in the i-th line equals Aij. The next n lines describe the matrix B in similar format...
The first line contains n (1≤n≤800). Each of the following n lines contain n integers -- the description of the matrix A. The j-th integer in the i-th line equals Aij. The next n lines describe the matrix B in similar format (0≤Aij,Bij≤109). Output For each tests: Print ...

I am working with sparse integer matrices to perform graph analytics with my Master's student @missvarhegyi. We have been trying to find a Java library supporting quick matrix-matrix (MM) and element-wise matrix multiplication operations...
The first matrix is an n × k matrix, while the second matrix is a k × m matrix. Therefore, theresult will be an n × m matrix. Use the read_int system call (syscall) to read in n, k, and m,as well as each unsigned integer matrix value.One approach you could take is to ...
