Finding the matrix entry wise product using element-wise multiplication

Here’s a Java program that finds the entrywise product of two matrices using element-wise multiplication:

   public class MatrixEntrywiseProduct {

    public static int[][] entrywiseProduct(int[][] matrix1, int[][] matrix2) {

        int rows = matrix1.length;

        int columns = matrix1[0].length;    

        int[][] result = new int[rows][columns];

        for (int i = 0; i < rows; i++) {

            for (int j = 0; j < columns; j++) {

                result[i][j] = matrix1[i][j] * matrix2[i][j];

            }

        }

        return result;

    }

    public static void main(String[] args) {

        int[][] matrix1 = { {1, 2, 3}, {4, 5, 6} };

        int[][] matrix2 = { {2, 3, 4}, {5, 6, 7} };

        int[][] productMatrix = entrywiseProduct(matrix1, matrix2);

        System.out.println("Matrix Entrywise Product:");

        for (int i = 0; i < productMatrix.length; i++) {

            for (int j = 0; j < productMatrix[0].length; j++) {

                System.out.print(productMatrix[i][j] + " ");

            }

            System.out.println();

        }

    }

}

In this program, the `entrywiseProduct` method takes two matrices as input and returns a new matrix that contains the entrywise product of the input matrices. The `main` method demonstrates how to use the `entrywiseProduct` method by providing two example matrices, `matrix1` and `matrix2`. The resulting product matrix is then printed to the console.

Note that the matrices used in the example are 2×3 matrices, but you can modify the code to work with matrices of different dimensions by adjusting the values in the `matrix1` and `matrix2` arrays.
