MATLAB: Removing certain rows from B using A as reference to produce C

newmatrixremoveselect

Hi everyone, I have A and B. I would like to use the values of A as reference to remove rows in B to get C

A =[11;
    12;     
    14;];
B = [9	45996;
     9	47540;
    12	49047;
    15	49151;
    12	53151;
    13	53239;
    10	56044;
    11	57046;
    14	57279;
    10	59286;
    10	59889;];

Answer C

c = [12	49047;
     12	53151;
     11	57046;
     14	57279;];

c = B(ismember(B(:,1),A),:)

MATLAB: Matrix C from A and B

If your algorithm is to remove all rows that are common to A and B, and we are assuming that these two matrices have the same number of columns, then try the following:

 A = [1 2 3; 4 5 6; 7 8 9; 10 20 30];
 B = [11 12 13; 4 5 6; 14 15 16; 7 8 9; 17 18 19];
 if size(A,2)==size(B,2)
   % get the intersection of A and B, i.e. all those rows that are common
   [Rows,IA,IB] = intersect(A,B,'rows');
   % Rows is a matrix of the rows common to A and B
   % IA is all the row numbers in A of those common rows
   % IB is all the row numbers in B of those common rows
   % remove all those common rows from A and B
   A(IA,:) = [];
   B(IB,:) = [];
   % concatenate what is left to get C
   C = [A;B];
 end

MATLAB: How do i display all the values of this for loop

for b = 1:ne
    c = 0 + (b)*a%remove ;

end

c=zeros(1,ne);
for b = 1:ne
    c(b) = 0 + (b)*a%remove ;
end
display(c);%all values stored and array
