Cholesky 怎么发音呀

penultimate

就是那个常用的 Cholesky 分解，Cholesky factorization，
最近想给人解释一下，竟然不知道准确的发音，糗大发啦，
坛子里的E文高手们，指导下呀

超里斯key     应该这么读，
这个分解主要是干什么的？我看程序的时候也是迷迷糊糊的 ^_^
给我的直观感觉是将力转化成位移，对吗？

In linear algebra, the Cholesky decomposition or Cholesky triangle is a decomposition of a symmetric, positive-definite matrix into the product of a lower triangular matrix and its conjugate transpose. It was discovered by André-Louis Cholesky for real matrices and is an example of a square root of a matrix. When it is applicable, the Cholesky decomposition is roughly twice as efficient as the LU decomposition for solving systems of linear equations.

The above is from Wiki.

Thanks to all who replied.  The question was how 'Choleski' was to be
pronounced (and, for those who verbalize to themselves as they type, how the
S-plus command 'chol' should be pronounced).

I had heard two pronunciations, 'Koleski' and 'Tsholeski', and wondered what
others had heard.  (By 'Tsh' I mean the sound heard in the English word
'church' or 'cha-cha-cha'.)

Of the seven who ventured a pronunciation, four offered 'Tsholeski' and
three 'Koleski'.  Some had comments:

For 'Tsholeski':

        "That's how I learned it."
        " 'Koleski' is very rare. ...  'Tsholeski' is nearest to what I have
heard." [This may be a disguised suggestion of 'Sholeski.']

For 'Koleski':

        "I've always heard Koleski."
        "I've only heard 'Koleski.'  I'm 95% sure that it's correct."

There does not seem to be any standard Anglicization.

The rest of this note draws mostly from a discussion about Cholesky on a
numerical analysis news list in 1990; it can be found on the Web by
searching for 'Cholesky pronunciation'.  There is also, as the help page for
the S-plus command 'chol' mentions, a short biographical note on Cholesky,
which I have not seen, in J. H. Maindonald's Statistical Computation (1984,
Wiley).

The 1990 discussion includes a eulogy of Cholesky by his colleague Benoit,
who saw to it that Cholesky's method was published after Cholesky's death.
The eulogy was translated in 1975 by Richard Cottle for Cholesky's
centennial.  Andre-Louis
Cholesky (spelled with a 'y'), born in France in 1875, was a geodesist in
the French military.  He developed his computational procedure to solve
geodetic problems, among which was, in the words of his eulogy, the "problem
of levelling in Morocco."  He died in battle in 1918.  Benoit published the
computational method in "Bulletin geodesique" in 1924.

The most likely French pronunciation of Cholesky is that heard in 'Chopin'
-- the English 'Sh' sound.  A less likely alternative is the English 'k',
heard in, for example, the French pronunciation of 'cholera.'

There were some statements in the 1990 discussion that the Cholesky family
was probably Polish.  A Polish correspondent stated that the original family
name was 'Cholewski', a family of "good Polish patriots" that had emigrated
to France.  The Polish name would be rendered in English, according to that
correspondent, as 'Holeski', which I take to have the throaty 'h' of
'hannukah' , also spelled in English as 'channukah.'  (A Russian
correspondent offered the spelling 'Kholeski' for this pronunciation.)
There is no record of whether the Cholesky family in France tried to retain
the original pronunciation or adopted the French 'Sh' pronunciation.  (A
French correspondent stated that he had had a student from this family, but
did not give the pronunciation.)

If, on the other hand, the Cholesky family was Russian, there are three
candidate Cyrillic letters that might have been transliterated into French
as 'Ch'.  One is the above-mentioned 'Kh' sound -- of 'hannukah'.  Another
is the 'Sh' sound, which would have fit into French pronunciation quite well
as 'Cholesky' and is found in such French spellings as 'Chostakovich' and
'Chalom Aleichem' (at least in the initial 'ch' in each case).  The third is
the English 'Ch' sound 'Tsh', which, however, is normally rendered in French
as 'Tch', as in 'Tchaikovski' or 'Tchekov.'

In summary:

1.  If you want the most likely French pronunciation, pronounce it
'Sholesky' as in 'Chopin.'

2.  If you want the most likely Polish pronunciation, pronounce it
'Kholesky' as in the initial 'h' in 'hannukah.'  English speakers who
don't want to use the guttural might opt for 'Holesky' or 'Kolesky'.

3.  If you go for the Russian, you have some leeway, not knowing the
Cyrillic spelling of the name.

4.  No matter what you say, many of your hearers will either tune you out or
think you wrong.

5.  If you want to spell it the way Andre-Louis spelled it, spell it with a
'y'.
