The Sultonov system indicator - page 114

To understand:

1) Y = AX is a closed system; (SLAU solution methods are applicable here)

2) Y = AX + B is an open system; (here methods of the solution of SLAU are not applicable)

Where

X -- vector of inputs

Y -- vector of outputs

A -- system matrix

B is a vector of "noise", a vector of external influences (a vector of free terms)

So do it if you have to. What's the point of all this idle babble...

everyone knows how to copy the wiki...

ZS I went to your profile.
The whole rating is due to comments. Not a single code.
Without a code your opinion is not authoritative for me.
Keep commenting...

I don't give a shit about ranking ;)))))))

I'm not making code to boost ratings, that's for sure ;))))))))

I need my code to solve my tasks, I definitely don't need someone else's code.

Always and everywhere I tell people that one must take knowledge from books, not wikipedia.

And to make a second indicator (for yourself!!!) -- it will be very useful for awareness and understanding, which at this stage you do not have.

 
Nikolai Semko:


This is your level of mathematics above grade 7.

 
 

You docents, you can't even formulate the problem properly, even the one you are solving for yourself. It is necessary to reinterpret it, to call constants with X's, and to give the name "a" to the variables you are looking for.

This is the system:

x0 = a0 + a1*x1 + a2*x2 + a3*x3

x1 = a0 + a1*x2 + a2*x3 + a3*x4 

x2 = a0 + a1*x3 + a2*x4 + a3*x5

It's the same as this one:

x0 = a0*X + a1*x1 + a2*x2 + a3*x3

x1 = a0*X + a1*x2 + a2*x3 + a3*x4 

x2 = a0*X + a1*x3 + a2*x4 + a3*x5

Where X=1.

So we have a system of three equations and four unknowns.

And if someone solves the wrong problem, it's not because he is a fool, but because you can not even formulate a trivial problem. Either you're sitting here for a joke or you're out of your mind, or maybe you have always been. I find no other explanation for your inability to articulate your task clearly.

 
Олег avtomat:

In brief: Gradient methods.

It's more detailed here.

There are also pointers to the literature.

One docent pretends to explain, the other pretends to understand.

 
Dmitry Fedoseev:

One docent pretends to explain, the other pretends to understand.

is your knowledge limited to the 7th grade too?

 
Олег avtomat:

5-ю. And why make a smartass of yourself with all sorts of "open systems", "closed systems", "composite terms", "vectors", "matrices" when everything is explained in 5th grade concepts? In 5th grade, they study systems of linear equations.

 
Hello Yusuf and the sittings! 😊
Yusuf, please freeze your robot's signal.
