Hello, friends in my this video. I am going to discuss about flip LR. And flip Judy comment, which is going to be very useful in different signal processing related projects which made which you may do in your signals and systems or in your digital signal processing course. Okay, see, suppose. I have one array a equal to suppose. Let me take four fives or a let me take simple 1 1 2 3 4 5 OK, then suppose you want to reverse the array. That is 5 4 3 2 1 If you want to get that array, then you know, we use flip lroff a right so basically, if you write B and enter C 5 4 3 2 1 this already. I have discussed in time reversal in of a signal in MATLAB. Right now, suppose you have one array like this? This is basically row vector. Rho Matrix. Suppose you want Polar Matrix. So 1 2 3 then Semicolon, then 14 5 Okay, then if you write a C, it is one vector so for this free pillar will not work why the name itself it is clear in our let me see left to right so what the function will do. This will convert the left element to the right right element to the layer that is let us write row design but is present so there is no less right concept is applicable for this particular thing what we can do if we want to define is if I want to get 5 element to the upward. So that means so that is flip UD. Okay, see from the working function itself. We can write if names simple, so basically be equal to flip beauty in this case. Suppose it is a column Vector Del Flip. Ud, we will use flip UDS. If you write C what you are getting be. Five, four, three, two one where my actual a was 1 2 3 4 5 so for reversing of the row matrix flip Ella for reversing of : matrix. Our column Vector V. Ud just have a note in this. This is very important if someone ask you to let us see so. Cbl to let me take 1 2 3 4 5 Which is basically 1 column matrix. If you write Beastie 1 2 3 4 5 Follow me, you are getting now. I am telling you you give me. 1 : Attrex, whose elements are 5 4 3 2 1 But we don’t you say flip you de Ville to sleep. Illa, so what do you know that flip? Eller is applicable only for Matrix into Row Matrix, so B 2 B transpose. So if you I’m supposed to column Matrix, you will get Rho Matrix right So now my B will be 1 2 3 4 Sighs all right now. You use to flip inner of B right so basically see now. B consists 5 4 3 2 1 Now what you can do Ideally, you just transpose so B equal to B transpose if you write CPD 5 4 3 2 1 so basically. If you want to flip your column vector using flip illah, then first, you have to take transpose. Then you can use flip pillar comment then again. P transpose ins. You will get the reverse any already perspective, diverse matrix. But if you went directly refers the colander simply use flip. Beauty, okay, so this you can use I am. Telling You one application like suppose. You were doing some prototype related for your signal processing and somewhere what you have to do. You know you first. This sound, okay, that is somewhere you might have hard This. Also that one song, which is from the entry beginning. If the song is pit, obviously it will we understand it. Suppose you want to that end of thing and you can split. Beauty, because who even put the audio signal we use or do we give these signal names? Suppose my signal may be suppose. Shawn simply saw. And that is MP4 file. Let us assume so like that. We write then. What do you do? We this we get the. Y as basically, we input the song in the MATLAB using this comment and Y will be one coulomb matrix or column Vector. Okay, so in that case. If you want to pair that song from the end, then that is simply you can use flip. Ud okay, so this application, this particular project application, I am going to discuss in my next video so heavy, clear understanding in this when I should use flip LR. And when you studios we Tod and this also, I have told you this. Also, you just have a note there if you want to use flip. Lr in the position of flip UD. Then you have to first take an suppose of the column, but fix. Then you have to differs using flip like this. You have to take a transpose simple, right, so this is all for my. This video is based on this trying to implement some code and evaluate this in MATLAB. He will make it. He will find it very easy, and it will be there in your mind for a longer period. Also, if you implement in, okay, not only to note, noting the only notebook is not sufficient for programming every time you have to implement whether we will consider in that layer or C or C++, or Java or PHP Python. Whatever you have to implement that whatever you want us to try to implement. Okay, which is all for my this video. Thank you for watching.
