MATLAB: Finding matched rows of matrix with other matrix

Question

Lets say we have two matrix.

A=[1 1]

B=[2 0;1 1;1 1;3 1]

Now second and third rows of B are same as matrix A. and I want to find indices of such rows. i.e 2 and 3

I have tried 'ismember' but it is giving just first matched row index i.e. 2 (code can be seen below)

Thanks

A=[1 1]
B=[2 0;1 1;1 1;3 1]
[L, M] = ismember(A,B, 'rows')

Answer 1

arr=[];

for i=1:size(B,1)

c=0;

for j=1:2

if B(i,j)==A(1,j)

c=c+1;

end

end

if c==2

arr=[arr i]

end

end

arr gives your required indices
