Finally of course ISSUE 1 division a divided by B of course that also can be done right.
A Florida version of course and that can be done.
Right.
So this is something which is highly cool about about non-pilot if I want you know all of them a a a
race to be is a bit of it does.
So it raises it to each each element in the others thing.
It's a beautiful thing for that.
But let's say if you wanted something Cholas matrix multiplication you remember matrix multiplication
is something different from normal multiplication.
See this multiplication which came near was nothing but 11 months bubur one is Levan two elements one
is 12 month number one is 13 and matics multiplication is not like that multiplication of the first.
So if you want the first element it is multiplication of the first row multiplied by the multiplication
with the first column of the second matrix.
So if it will be something like this Levin multiplied by 1 plus 12 multiplied by 1 that is low interest.
Well it's how much that's going to be 23 correct plus Claudian multiply by 1.
Plus 13 is 36 right.
So that's how it's going to be.
So how do I get 0 metrics multiplication that's done.
So if I put up all my down here saying matrix multiplication
right I could get something done like this by saying that I could do it because it is a dot product
cycle say dot dot and I see a comma B.
Right.
And if I do that there you are 36 then 6:36 6:6 because all of them are almost the same because 11 12
13.
Multiply that one to three all ones it's the same thing so you are going to get the same values.
That's about matrix multiplication correct.
These are a few things that we get to learn when we when we learn about yes.
OK the dot product and stuff like that right now.
Now let's.
This is about to is about this.
Now let's also see if you can do a dot product with it you know which you you know right that the doctor
can be done only with a shape if it is equal or basically the number of the number of rows in the first
should be equal to the number of columns in the second.
Or something like that.
It's that's the rule for the dot product and you must be careful when you do that.
OK.
Well if you want to duck right in the two dimensional.
So we just saw the two dimensional case of a dot product.
If you want to see a dot product in the three dimensional case if you if you have an interest to show
that to you to how to get a dot product in the freedom and show case so let's say import non-Thai as
MP.
And the reason I'm creating an RTX.
But because I'm creating a three dimensional let me just be careful with what I create.
I'm going to be very professional in creating this up.
So I see an endo.
And and then I if I define and Anto come
write something like this.
So this is how I need to create them.
So let's say for example I say three come on one come two.
OK.
I need inside this right.
I'm going to create inside this one I'm going to create multiple that is.
So I'm going to say something like this.
Cool.
So let me just this is one this is another one which I'm going to create.
And and of course that is one to close this up right.
And that's that's the part part about it.
So I can just put this up here.
Let me say this is going to be the end all five come to come at three.
And there's going to be let me if you want to create one more in this it's going to be oh that's going
to be huge.
And so you have you know come one come on one page.
So this is how you you get some surprises like this.
Yeah and here in this particular case it will be.
So here I've completed this and I've completed I've completed this too.
Now in this again I'm going to have this one and then I'm going to have one more.
I'm going to have one more break.
So we're here it's going to be let's say three come on to come up for.
And then let me say to come one come or find me say Tricom or five come afore right and then OK let's
not have more than three it's going to be hugely time consuming and energy consuming.
Right.
So I would.
And then to sort of be something like again over here three of them three of them here to create.
So this is a three dimensional attic to the
and of course so does your entire
lizard entirety I can create a Y which is going to be say Y is equal to and b I'm not going to create
it.
Once again I'm just silly ones like like like x.
So if I print X then print y.
That's what I'm going to get.
Hugely right.
And of course with the dot dot dot dot and I say X come a y it hugely does the entire process for me
for the entire dot.
That's the amazing part of being.
Being able to do it in them.
That's that's that's beautiful.
That's awesome.
And you know this is something which I want you all to figure out too about how to use them in detail
how to get your problems done and stuff like that.
OK.
So that's about that's about tristesse that's about non-coding areas and how you can multiply them how
you can use them.
But you have just complete the arithmetic operators and.
Of course we have a huge thing coming up with how you know need to remember an umpire is an awkward
crisis because because that's why I said if I if I multiply of course I told you right.
If there was an A and if I multiply it would be.
So if it is a this is your a right.
And if this is your B and if I do a multiplied by B sorry if multiplied by B.
You know I would get element by element multiplication Levin must have a one term much lower one.
This does not happen twice.
So this is hugely different but if you want to use an umpire address that tries are you want to create
new mitrailleuses in that particular fashion then what you can do is you can you can do something like.
You can say and Dot create and try slate so I can use Matt.
Matt and I pass a and I'm going to say this is going to be a trace of a face or mitrailleuses of B can
be graded by also saying that Mattos
Bombay.
Right.
And after this.
Now if I do am a multiplied by and B and if it ends up right if I print I mean multiply them B.
Now this is going to be a very different case to not be a multiplier because now this is Max matics
multiplication which is going to be dot product multiplication.
So here you have no Emmi and inby are now mitrailleuses right.
So this is about the arithmetic operators.
We're going to look at comparison operators and a few other operators in the tonal rights but hope you
understood this much.
Thank you.
