comparing the two column in MATLAB

143 views (last 30 days)
Hello!
Let, A=[ 1 2 ; 2 2; 3 4; 4 4]
I want to compare the 1st column with the 2nd column to find out if there is any row having the same values in both columns.
Say, in the example, 2nd and 4th rows have the same values in both the two columns. i need to find the rows where the condition is satisfied.
Could you please help me?

rowswithidenticalvalues=find(A(:,1)==A(:,2)) %1 indicates the values are the same
