Using the Streaming SIMD Extensions, you can complete a matrix multiplication with only 16 products and 12 additions. The library provided in this article was written with the goal to get the most out of the Streaming SIMD Extensions, and to reduce the amount of time needed for matrix/vector ...
Use -st flag to run this application using single thread. For single thread option I've ovreloaded * operator for class matrix. It implements straightforward solution with 3 for-cyclus (O(n^3) complexity). Multithreaded multiplication Use -mt flag to run this application in multithreaded mode....

publicoverrideIntPtr ClassHandle {get; } Property Value IntPtr The pointer to the Objective-C class. Remarks Each Xamarin.iOS class mirrors an unmanaged Objective-C class. This value contains the pointer to the Objective-C class, it is similar to calling objc_getClass with the object name....
MatrixProduct and helper method MatrixCreate, as shown inFigure 3. The demo uses a brute force approach, but because the calculation of each cell in the result matrix is independent, matrix multiplication could be performed in parallel using the Parallel.For method from the .NET Task Parallel ...
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...
