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...

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...
Most modern high level programming languages such as Fortran, C++, MATLAB, Python, C#, Java, .etc., have programming constructs that deal with the parallel processing. In this research paper, the programming language that has been chosen is C# and the experiment is the multiplication of two ...
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...
