Hello Matlab Users,
  • I have a A matrix:
  • A=[2 4;2 10;2 15;5 14;6 7;6 15;8 16;8 10] and I want to see the first row where I meet let's say "6"(which is the 5th row).Could you help me in solving that problem,please?

idx=find(any(A==6,2),1)

you can use the find() function and search for when the first column in A contains "6".
