Accepted answer

for k=1:size(B,1) if isequal(B(k:k+1,:),A) idx=k break end end B(idx:idx+1,:)=[]

Thanks for the response,

but i think there must be a simple solution as for the vector we have B(ismember(B,A)) = []; it works for the vector, i think there should be a solution for the matrix

in your case:

B = randi(100,10,62); A = B(4:5,:); B(end,:) = A(1,:); % your data

[a,ii] = ismember(B,A,'rows'); iii = 1:size(A,1); i1 = strfind(ii(:)',iii) + iii - 1; B(i1,:) = [];
