Using Java Eclipse IDE write the following program:

(Algebra: add two matrices) Write a method to add two matrices. The header of the method is as follows:

public static double [][] addMatrix(double[][] a, double [][] b)

In order to be added, the two matrices must have the same dimensions and the same or compatible types of elements. Let c be the resulting matrix. Each element cij is aij + bij . For example, for two 3 x 3 matrices a and b, c is
