MATLAB: Integrate new rows inside matrix and repeating them

digital image processingimage processingmatrixmatrix manipulation

I want to integrate two lines inside matrix and repeated frequently before each rows:
The original matrix:
A = [ G1 X8 Y118
      G1 X8 Y135
      G1 X 8 Y 150
      G1 X 8 Y 172
      G1 X 8 Y 209
      G1 X 8 Y 242
      G1 X 8 Y 410
      G1 X 9 Y 208
 ……..      ]  so on
Generated matrix 
AA = [ 
M 802
M 800 P 8
G1 X8 Y118
M802   
M800 P8   
G1 X8 Y135    
M 802   
M 800 P 8   
G1 X 8 Y 150   
M 802  
M 800 P 8    
G1 X 8 Y 172    
M 802   
M 800 P 8    
G1 X 8 Y 209    
M 802    
M 800 P 8    
G1 X 8 Y 242    
M 802   
M 800 P 8    
G1 X 8 Y 410      
M 802  
M 800 P 8 
G1 X 9 Y 208 
  …………] so on
So before any row, put these two rows
M802
M800 P8
How can we do this?

Here is the code to integrate two lines inside matrix and repeated frequently before each rows.
A = [ "G"+1 "X"+8 "Y"+118
    "G"+1 "X"+8 "Y"+135
    "G"+1 "X"+8 "Y"+150
    "G"+1 "X"+8 "Y"+170
    "G"+1 "X"+8 "Y"+209];
Repeat1 = ["M"+802,"","";"M"+800, "P"+8,""];
rows = size(A,1);
AA = [];
for i = 1:rows
    AA = [AA; vertcat(Repeat1, A(i,:))]
end
