My task is to fill in all of these constructors with the code needed without errors.

Write a class Matrix in Matrix.java that represents a Matrix. The type of each entry is a double. - public Matrix(int rows, int columns) -- Initialize a matrix of dimension rows x columns with all entries as zero. - public Matrix(double data[][]) -- Initializes a matrix with a provided two dimensional array of data. Here's a code snippet to initialize a 23 array for testing purposes: double test_2d_array [][]={{1,2,3},{4,5,6}}; - public double get(int row, int col) -- Retrieve the entry at the given row and column - public void set(int row, int col, double value) -- Set the entry at the given row and column to the given value - public Matrix add(Matrix other) -- Return a new matrix that is the result of adding this matrix with the other one - public Matrix sub(Matrix other) -- Return a new matrix that is the result of this matrix subtracting the other one - public Matrix scalarmul(double scalar) -- Return a new matrix that is the result of the scalar multiplication of this matrix with the given scalar - public Matrix transpose() -- Return a new matrix that is the result of transposing this matrix In addition to writing the Matrix class, you will need to write a main method in order to test it. Your main method will not be executed and graded, however. Refer to DogTemplateClass.java and other java files created in lecture. These files are on canvas. And don't forget labs are collaborative and much easier if you work with others! Submit Matrix.java to Canvas > Assignments > Lab3
