Solving.

Kinda like make it solve

1A + 2B = 0

3A + 1B = 0

 

solve for A and B.

 

In my case I am looking to find the instantaneous temperature in each wall layer during each hour of the day so yeah... each layer's temperature is a unknown that must be computed.

So something like this?

http://www.mathworks.com/help/matlab/ref/mldivide.html

 

i.e.

x = [1, 2; 3, 1] \ [0; 0]

 

Sorry, I don't have MATLAB installed on this computer at the moment.

Matlab was hiring today, if I saw your message, I could have went to them and asked lol

 

but sorry, I do not

So you're going to lie in your review? :confused_face_2:

Uhh NOPE, but when I say epic I mean very detailed. I would never lie -.- shame on you and thankfully the AD A900x sounds pretty damn awesome so it won't b hard to get nice a detailed with it [like my 8 page DT 880 review] 

 
But Lie, cmon deadly that's just MEAN I already have the Headphone and the OK to keep it from them, I have no reason to muddle my reputation by lying.

My bad.

 

I thought you'd make it sound epic, not make an epic review out of it. :p

Bad form for linking to the worst quality manga reading site.

Yea I should have worded that better, lol sorry as well

 

 and thanks. But still... it sounds like a DT 990 and a DT 880 had a baby! The BASS of a Dt 990 with the DT 880 balance [as it has less bass than a DT 990 but it's just as tight and a little deeper] Honestly what REALLY sucks q.q is these are better with classical than the Dt 990 and Dt 880, but they are not quiet up to par for EDM as the DT 990

How did I not notice this earlier?!

I played the **** out of this game.
The small dating-sim parts are refreshing :P

Almost too beautiful :'(



So today I drove my brother and his girlfriend around in Hamburg for like 8 hours (they are looking for a new flat and had to meet some people etc)
It was SO horrible!
I hate driving around in this huge, confusing city.
Really happy I'm finally home again.
Oh but one good thing happened! I stumbled upon a pretty big Asia Store and bought some Mochi, Ramen and Udon ;)

Eff this... getting MATLAB. (not getting mathematica since my school doesn't seem to like it that much, even in the maths dept.)

I can see why they think that. For really advanced stuff MATLAB is faster. I personally would prefer using a combination of Mathematica and C++, but it depends entirely on what kind of math you're doing and what you're used to.
Mathematica is pretty great for its user friendliness and intuitive coding, but it's also less fast for really complicated stuff -- not that you'll come across those sorta things in your undergraduate degree more than once or twice I think.

how do you guys feel about copy & pasteing when writing code... starting to get into passing arguments and modules in my intro programming class and I don't really copy and paste that much, I find it equally as fast to type and correct rather than fumble with my mouse to highlight the code and then paste it and read over to make the corrections?

Found an article with some examples of very simple copyPaste errors my question is, should I just stick with typeing and correcting or get in a habbit of... safe copy n paste editing? 

The huge advantage of not copy-pasting is that you'll be able to type recurrent lines of code more quickly, and become more familiar with them. This goes without saying only to a certain point -- if you're writing the same 10 line code a hundred times you might want to use copy-paste instead.

I might just have MATLAB do the calculations and I'll draw the graphs using Tikz.



Nope, they ain't.




In Mathematica it looks much better in my opinion. Plus, you can customize a lot of things in the display, though not as much as I'd personally like. For example changing the fonts in display can only be done to a limited amount, and plot legends and axis labels have very few customization options in terms of style. But one thing that is great is that I can combine arbitrary graphics objects really easy (e.g. combining parametric plots with vector fields, adding random circles or points, combining plots with list plots (data plots))

Speaking of MATLAB--help please! Q_Q
I really don't remember crap about matrices and arrays...
How do you use MATLAB to solve an X by X matrix with X unknowns? If anyone can show me with a smaller sized example I'd be really grateful... my upcoming project will need probably along the lines of 40x40 sized matrix and I really don't remember how...

https://en.wikipedia.org/wiki/Cramer%27s_rule

Use that, and do it with pen and paper like a real man!

In mathematica you'd just type out the matrix and say: solve this f*er for this vector!

you mean a system of linear equations with X unknowns?

In what basis?
In what space?
Using which algebra?

Thanks, I'm just not a fan of copy and paste, it just seems... accident prone. But I do see the point. I may get to the point where I crop in whole modules and edit them that way, but as far as creating new modules all together, seems better to code it entirely off hand. Then copy the entire module into another program if I need it, although I'm a net working student, I don't plan to be a programmer professionally. Just want to know it so I can do my own trouble shooting to some extent. 

Also I'm REALLY impressed by the AD 900x Bass :O it's a little too lean imo, but DAMN for EDM it's kickin the entire can feels like a linear DT 990, FUN but still balanced!  and it's equally as comfy, although it does slide around a smidge, although that doesn't seem to  have to much of a bearing on the sound  that and I need another hair cut when I have lot's of hair the wing system doesn't agree with my head to much.

I'm hitting a new kind of high low.

I've been working for 13 hours today. And when taking a break I feel like I'm being lazy. I feel bored immediately and feel like getting back to work, whereas while I'm working I'm not particularly enjoying it either.


Now I finally understand why they call workaholics 'workaholics'. I don't necessarily enjoy it, but I feel a dependency for it; it is an addiction of some sorts.

This is a feeling that is absolutely unfamiliar to me.


If I don't have to do it, I won't. If I have to do it, I'll make it quick

-.- I am so sorry to hear that but sadly it seems to fit your personality >< which is not an insult at all, you  seem like a very  focused and determined person!

 
Still it's 3:41 pm and I've got some home work I ought to be doing... *goes back to reviewing his AD 900x* :3 I'll get to it some times today though honestly... then I'ma start playing Pikmin 3 :D
 
Oh yea I'm excited! There's a new Batman open World game coming out AND watch Dogs! I'll have 4 EPIC open worlds games to explore :3
 
pikmin 3
Batman Arkam City
Batman Origins
Watch Dogs
 
all for my useless Wii U, which had to wait like 8 months to get some decent games for it [but the Wii U is a Netflix GOD :D my little Touch Screen Controller can STREAM VIDEO HAHAHAHAHAHAHA so SUCK it Ps3 and pc user]

Wow.
Have fun with your 800x600 6 inch screen.
