uhh, wouldn't adding the three elementary matricies, and taking the rref, give you the inverse? I just don't know where to go from there
ok, no idea what you're writing, but the numbers come out to be the same inverse that I got after doing the Gauss-Jordan Algorithm But a little English would be nice. If we don't interact, I have no clue what you're writing
Now second part !
I take that back, the numbers are a little different
I have just compute the inverse matrix with an individual method. Now we should follow the second part.
By adding these three columns: 1 0 0 0 1 0 0 0 1 to my original matrix and row reducing, I get that matrix as my inverse. I'm unfamiliar with your technique.
While you have good intentions, just writing the answer with no explanation does me no good since I not only do not learn anything, but I do not know what you are doing. Could you please slow down to explain? Also, just writing out the solution is against the CoC.
Don't attend to inverse matrix. Just follow the second part. suppose I got it.
Is it clear?
I think Mahmit is being really painstaking in trying to explain this. Good work.
Very nice question. I was really enjoyed. And I hope you could understand it.
I try to give you the same one.
I always thought how a software can find the polynomial with passing some points and some particular slope. So I figure it out. Thank you.
Umm, sure, although don't you think writing an actual program, the language (C++, Java, D, Ruby, Python, etc) doesn't matter, would be easier than doing this by hand every time?
I must find out some polynomial for a control system online. I have information with y, y' y'',... y(n). This problem help me a lot.
Indeed. very interesting.
