Thread: Why cant I call on the array I returned in the main method?

//matrix1
   double[][] matrix1 = {{1, 2, 3},{4, 5, 6},{7, 8, 9}};      
 
//matrix2
   double[][] matrix2 = {{0, 2, 4},{1, 4.5, 2.2},{1.1, 4.3, 5.2}};   
 
   addMatrix(matrix1, matrix2);
 
   printArrays(matrix1, matrix2, result, '+');
 
 
  }//end of main
 
    public static double[][] addMatrix(double[][] a, double[][] b){
 
double[][] result = {{a[0][0]+b[0][0], a[0][1]+b[0][1], a[0][2]+b[0][2]},
    {a[1][0]+b[1][0], a[1][1]+b[1][1], a[1][2]+b[1][2]},
    {a[2][0]+b[2][0], a[2][1]+b[2][1], a[2][2]+b[2][2]}};
 
return result;
}
 
    public static void printArrays(double[][] m1, double[][] m2, double[][] m3, char op)
{
for (int i = 0; i < m1.length; i++) {
for (int j = 0; j < m1[0].length; j++) {
System.out.print(" " + m1[i][j]);
}
if (i == m1.length / 2)
System.out.print(" " + op + " ");
else {
System.out.print(" ");
}
for (int j = 0; j < m2[0].length; j++) {
System.out.print(" " + m2[i][j]);
}
if (i == m1.length / 2)
System.out.print(" = ");
else {
System.out.print(" ");
}
for (int j = 0; j < m3[0].length; j++) {
System.out.print(" " + m3[i][j]);
}
System.out.println();
}
} 
//    public static void printArrays(double[][] a) {                        
//        for(int row = 0; row < a.length; row++){
//        for (int col = 0; col < a[row].length; col++) {
//            
//            System.out.print(a[row][col] + " ");
//        }//end of inner for loop
//        System.out.println("");
//        
//}//end of outer for loop
//    }//end of printArrays
 
    }//end of class

In my method addMatrix I return the array result. I then try to call it in my main method to print out, however it gives me an error saying it cannot find the variable. Since I returned it shouldnt I be able to call it?
