Finding the matrix hyperbolic tangent

Here’s an example Java program that finds the hyperbolic tangent of each element in a matrix:

  import java.util.Arrays;

  public class MatrixHyperbolicTangent {

    public static void main(String[] args) {

        double[][] matrix = {

                {1.0, 2.0, 3.0},

                {4.0, 5.0, 6.0},

                {7.0, 8.0, 9.0}

        };

        double[][] result = calculateMatrixHyperbolicTangent(matrix);

        System.out.println("Original Matrix:");

        printMatrix(matrix);

        System.out.println("Hyperbolic Tangent Matrix:");

        printMatrix(result);

    }

    public static double[][] calculateMatrixHyperbolicTangent(double[][] matrix) {

        int rows = matrix.length;

        int columns = matrix[0].length;

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

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

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

                result[i][j] = Math.tanh(matrix[i][j]);

            }

        }

        return result;

    }

    public static void printMatrix(double[][] matrix) {

        for (double[] row : matrix) {

            System.out.println(Arrays.toString(row));

        }

        System.out.println();

    }

}

In this program, the `calculateMatrixHyperbolicTangent` method takes a matrix as input and calculates the hyperbolic tangent for each element using the `Math.tanh()` function. The resulting matrix is then returned.

The program demonstrates the usage of this method by creating a sample matrix, calculating the hyperbolic tangent matrix, and printing both the original and resulting matrices to the console.

Note: This program assumes that the input matrix is a 2D array of doubles. You can modify the program as per your needs to handle different data types or matrix dimensions
