It has both implementation of matrix multiplication- one without multi-threading and another one using multi-threading. 1) Condition for multiplication of two matrices is -1st matrix column number equal to 2nd matrix row number. 1) Read row, column numbers of the two matrices and checks the column number of matrix1 =row number of matrix2.If condition true then insert the elements into the matrices using while loop. Next, we used the For Loop to iterate those matrix values. A matrix is also known as array of arrays. Java program to multiply two matrices, before multiplication, we check whether they can be multiplied or not. Part I was about simple matrix multiplication algorithms and Part II was about the Strassen algorithm. Matrix multiplication is not commutative. To Perform Matrix Operations-Addition and Multiplication. Also, this approach isn't efficient for sparse matrices, which contains a large number of elements as zero. a) Insert the elements at matrix1 using two for loops: b) Similarly insert the elements at matrix2 using 2 loops with the structures for (i=0;i C_ij as a naive solution. For multi-threading implementation, I used Java's Executor Framework. We can add, subtract and multiply matrices. Mail us on email@example.com, to get more information about given services. insert sum value in to the resultant matrix at res[i][j]. The compiler has been added so that you can execute the given programs yourself, alongside suitable examples and sample outputs. If condition is true then Enter number of rows and columns of first matrix : 2 2 Enter first matrix elements : 2 4 6 8 Enter number of rows and columns of second matrix :2 2 Enter second matrix elements : 3 6 9 12 Matrix multiplication result is : 42 60 90 132 Java Examples - Matrix multiplication. The second program takes any two numbers (can be integer or floating point) and displays the result. We can multiply two matrices in java using binary * operator and executing another loop. Also read â matrix transpose in java In this tutorial, we'll have a look at how we can multiply two matrices in Java. Now multiply the array elements as matrix. When two Matrices P & Q of order a*b and b*c are multiplied, the resultant matrix will be of the order a*c. Here, the a entries across a row of P are multiplied with the b entries down a column of Q to produce the entry of PQ. The example given below explains the multiplication between two 2*2 matrices. 3) Print the matrix using while loops with the conditions i C_ij as a naive solution the processor can leverage multiple compute resources to tackle larger problems a...
