Not much time to talk about the Matrix, but actually The Matrix is something like the list, but it
is sometimes called Arae or multidimensional array or something like that.
Got some programming languages like the C++ or C C Charbroil.
I think Java itself also used the concept or the term eRate not list.
OK, but anyway, they are the same sometimes in a lot of cases or a lot of things.
Just naming nothing, no big deal.
OK, so let's put this matrix.
To create it now, I open a brackets.
Square brackets, but this time I will put brackets like this.
So put this and put this and this, put this OK as well.
Now, I know you may get confused, but follow me for now and I will explain everything indicates so
one, two, three, and here about four, five, six and about.
Seven, eight, nine.
All right, OK.
No, I want to print some values from here, right?
Yes, this is what they're all about.
So, Brent, using the print function now, I will use the Matrix.
So far, so good, right?
Nothing new.
Now, this is the new things that have been added here, which is using two brackets.
Two square brackets?
No, actually, it's very simple, just imagine with me now, this is the first line.
This is the second line.
And this is the third line.
Do you get it or not?
Yeah, actually, you are right, this is zero and this is one and this is to OK, no inside zero.
Which is this one, we have zero.
One, two, OK.
I mean, as an index, I mean, don't get confused between the numbers, so actually it's better to
use A, B, C, yeah, actually like this.
So I want from the first line, which is zero.
OK, the first sequence or the first list, which is zero, I want to be OK.
So which is zero one.
So I would put one.
So this will bring the B character.
Let's check this out from here.
You can see that it is not defined.
All right.
Do you know why this happened?
Yeah, because because actually, I bought it as a rate as a variable is actually not as a value, so
I need to provide that single quotation or the double quotation, by the way, because I want it to
be as a character, not as a variable.
So if I don't put that, actually, it will be considered as a variable.
And actually, it is good that happened and we see we saw that by practice, that we need to be careful.
OK.
All right.
Now let's check what would happen.
Let's clear the screen first.
And here you can see that we print the.
And this is the same thing, if you want to print a so, for example, you want to print BNC, so you
will vote here, quote on quote, I like this and you want it.
So zero one two.
So it will be three Y equals three minus one.
Equal two, which is zero one two.
So B and C, this would print B and C.
Let's check this out actually.
Yeah, you can see that it is now BNC, what actually the Matrix and these cases is very complex and
subject.
So actually you can use that for the screen boxes or using image processing and a lot of things, actually
deep learning.
And but in this case, we don't need to handle that in detail because after all, we are writing an
ethical hacking tools, not something for A.I. or data sets.
OK, thanks for watching.
