Finding the matrix inverse hyperbolic cosine.

Here’s a Java program that finds the matrix inverse hyperbolic cosine:

 import java.util.Arrays;

  public class MatrixInverseHyperbolicCosine {

    public static void main(String[] args) {

        // Example matrix

        double[][] matrix = {

                {2, 3, 4},

                {5, 6, 7},

                {8, 9, 10}

        };

        double[][] inverseHyperbolicCosineMatrix = findInverseHyperbolicCosineMatrix(matrix);

        // Print the resulting matrix

        for (double[] row : inverseHyperbolicCosineMatrix) {

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

        }
    }

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

        int n = matrix.length;

        // Create a new matrix to store the results

        double[][] result = new double[n][n];

        // Calculate inverse hyperbolic cosine for each element of the matrix

        for (int i = 0; i < n; i++) {

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

                result[i][j] = inverseHyperbolicCosine(matrix[i][j]);

            }
        }

        return result;

    }

    public static double inverseHyperbolicCosine(double x) {

        // Calculate inverse hyperbolic cosine using the formula

        double result = Math.log(x + Math.sqrt(x * x - 1));

        return result;

    }

}

In this example, we have a 3×3 matrix as input. The `findInverseHyperbolicCosineMatrix` method calculates the inverse hyperbolic cosine for each element of the matrix using the `inverseHyperbolicCosine` method. The resulting matrix is then printed to the console. You can modify the `matrix` array with your desired values or extend the program to handle matrices of different sizes.
