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 current matrix multiplication system will able to provide results of any desired matrix size. Users will be also provided with options to choose the matrix size before entering the elements value for that particular matrix. Once the matrix size has been entered for both matrices, you will ha...
We give out the principle of matrix parallel computing.We describe the algorthm with JAVA Language,and analysis it into excellence.The program expressed the good charateristic in a computer with many CPUs.In the text we give out a kind of new way of thinking:use the JAVA multi-threading to...

ParserNG of course allows matrix multiplication with ease. To multiply 2 matrices in 1 step: Do, MathExpression mulExpr = new MathExpression("M=@(3,3)(3,4,1,2,4,7,9,1,-2);N=@(3,3)(4,1,8,2,1,3,5,1,9); P=matrix_mul(M,N);P;"); System.out.println("soln: "+mulEx...
Performance: overhead of using java/jna? Dense You can use the 'dummy_mmul' method of DenseMatrix to measure the overhead. It makes a call, with two matrices, right through to the native layer, doing everything that would be done for a real multiplication, but not actually calling the...
