I'm looking for c/c++/java/basic code for QR Decomposition.
The numerical recipes code only handles square matrices.

Hi,
I've several methods which get large objects as parameters like:
qr_decomposition(const DenseMatrix &A)
My question is simple: Should the line above be the preferred way or
should the parameter be given like
qr_decomposition(DoubleDenseMatrix A)

Does anyone know where to find an implementation in C of the
Dulmage-Mendelsohn decomposition of a sparse matrix, like the 'dmperm'
command in MATLAB?
Thanks,

Just wondering if anyone out there has any code to convert a plural word to
it's singular form and vice versa. Most of our database tables are named in
a plural fashion. When we go to create templates to select a single record,
we end up with a class name that sounds as if it's a collection instead of
just one data object. Just wondering if...

In my current work I noticed that I have several circumstances where I need
to create little if/else constructs to handle the phrasing of a message.
This typically involves a ternary situation like this example illustrates:
0 files were downloaded (or No files were downloaded)
1 file was downloaded
2 files were downloaded
They're all very...

This might seem like a trivial thing, but has anyone has come up with a
better way of outputting a singular vs. plural string?
For example:
// default plural label
$string = "appointments";
// singular label
if (mysql_num_rows($results) == 1) $string = "appointment";
print mysql_num_rows($results) . $string;

I am designing a new table with a few columns that may or may not have
a value on each row that is inserted.
What issues determine whether to allow a NULL value to be inserted for
that column or define a default value to be used?
I want to think through the repercussions of this decision before I get
into production.

Hi,
I'm wondering where I may get the C source code for a
linear-algebraic technique known as the singular value decomposition
(SVD).
I found the code (a function called svdcmp) from Numerical Recipes
in C (by Press, Teukolskyk, Vetterling, and Flannery). However, it
always yields a wrong n-by-n V matrix after decomposing the original...

Hi
I am currently working on figuring out a code for performing a singular value decomposition for String arrays.
Can some one help me get started on this. I have already done a declaration for the array of dimension 5000X3000. Now i need to perform the function on the array.
Thanks a lot in advance.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
