I have two matrices A and B.
A = [1 2 3; 4 5 6; 7 8 9]
B = [1 3 20 2; 1 2 3 55; 7 8 9 10; 88 2 1 5]
and I need to extract the rows in B matrix with common elements in A matrix, row by row.
The result shall be like that:
common_rows = [1 3 20 2; 1 2 3 55; 7 8 9 10]
Thanks.

A = [1 2 3; 4 5 6; 7 8 9];
B = [1 3 20 2; 1 2 3 55; 7 8 9 10; 88 2 1 5];
%Indices of rows in B
idx = 1:size(B,1);
for k=idx
%If elements in a row of B are not common with all elements of any row
%in A, remove that row index
if ~any(all(ismember(A, B(k,:)),2))
idx = setdiff(idx, k);
end
end
idx
C = B(idx, :)
