Need help with a matlab function. I have to implement a QR decomposition using givens rotations. The implementation has to use the matlab function "planerot" and the only implementation on stackoverflow that I found did not use this function.

That the special case for 2x2 matrices, and it can be used to compute the important values in an arbitrary nxn Givens-matrix (the remaining entries are 0 except for the main diagonal which are 1).
So if you multiply the whole rotation matrix, say
[math]\begin{pmatrix}
c &-s & 0 & 0 \\
s & c & 0 & 0 \\
0 & 0 & 1 & 0 \\
0 & 0 & 0 & 1
\end{pmatrix}
\begin{pmatrix}
a_1 & a_2 & a_3 & a_4 \\
b_1 & b_2 & b_3 & b_4 \\
c_1 & c_2 & c_3 & c_4 \\
d_1 & d_2 & d_3 & d_4
\end{pmatrix}
=
\begin{pmatrix}
* & * & * & * \\
0 & * & * & * \\
c_1 & c_2 & c_3 & c_4 \\
d_1 & d_2 & d_3 & d_4
\end{pmatrix}[/math]
Note how you only need to compute two rows (*), you don't actually need the whole Givens-matrix.
Or perhaps you only use planerot to compute the whole Givens-matrix and can use it in the next steps.

Can someone help me find the original Fate/stay night eroge visual novel (Not the Realta Nua version!). I tried getting it from mirror moon website, and torrent, but those versions required that I have the original CD (which I dont have, so I can use them). I know it exists, since I had it on my older laptop, a few years ago.

lol no. It's an action VN with like half a dozen mildly pornographic scenes that end in less than a minute; it's not an eroge.

A while ago, someone mentioned an anime on /a/ called something...underground.
I managed to see part of the first episode and it's about some kids that live in an orphanage digging for treasure. The episode starts with one of them finding another person and a fight ensues.
I cannot for the life of me remember the name. It came out within the last few months, IIRC.
Any help in finding it is appreciated. Pic unrelated.

I just finished Boku Girl and REALLY want another manga/anime like it.
I try using the "gender bender" tag, but that just brings up a bunch of crossdressing nonsense instead of actual gender change.
Not to be picky, but preferably one that doesn't look like some Korean shit where everyone has super long slender limbs and weird faces that are incredibly unappealing.
I tried Shishunki Bitter Change but that ended up being super depressing. Especially the ending. I hate it.

Kashimashi: Girl Meets Girl, it could be considered shoujo ai tho (don't kill me /u/). There is an anime adaptation that is good until de churistmas episode.
Also, it is crossdressing, but Prunus Girl is pretty good, maybe you want to give it a chance.
>>
>>367217
I will check it out ASAP! Not craaaazy on the artstyle, but beggars can't be choosers.
As far as Prunus Girl goes, I'm willing to give it a shot, though even with crossdressing stuff, I usually prefer the changed person to be the protag.

I need the combined powers of your autism. Cute girl and I at work have been sending each other coded messages. Her latest one has me stumped:
TNUROHECDSIIHEOSSHRLOMATV
The only things I know so far:
-likely not a caesarian cipher. Already tried shifts 1-25 forward and backwards. Unless it's that AND scrambled.
-double IIs and double SSs likely significant. HE also repeats twice
-it is in English and not another language, and is also something intelligible and not a bunch of gibberish
I've been stuck on this for two days. We're racing to see who can figure out the other's first. If anyone can help me crack it I will be eternally grateful.
Caveat: this is my first ever post on 4chan, so if there's a better spot for me to post this just point the way
