How to find maximums in matrix

Hello.I have this matrix A=[116 3;107 6;114 6;119 6;117 9;120 9;108 15 ;113 18;115 18;112 21;111 24].I want to detect local maximums from second column and where local max happened that row should be kept in a new matrix.here (112 21) & (111 24) should be saved in matrix B.i want to do this with for loop and max function.can any one help me plz?

%if true
 local_max_maatrix=zeros(size(A,1),2)
 local_max_maatrix(end,1)=A(end,1)
 local_max_maatrix(end,2)=A(end,2)
 threshold_max=3;
for eee=2:size(A,1);
     [CC,II] = max(A(eee,2))
     if CC-A(eee-1)>threshold_max;
         local_max_maatrix(ee,1)=A(ee,1);
         local_max_maatrix(ee,2)=A(ee,2);
         A(II,:)=[]
     end
 end

%end

What is your definition of a local maximum? In your example matrix, 21 is not a local maximum under any established definition of the term.
