How do I iterate through each element in an n-dimensional matrim>x m> in MATLAB?
... problem. I need to iterate through every element in an n-dimensional matrim>x m> in MATLAB. The problem is, I don't know how to do this for an arbitrary number of dimensions. I know I can say

Can an enum class be converted to the underlying type?
...m class to its underlying integral type:
template<typename E>
constem>x m>pr auto to_integral(E e) -> typename std::underlying_type<E>::type
{
return static_cast<typename std::underlying_type<E>::type>(e);
}
then use it:
auto value = to_integral(my_fields::field);

What's the difference between String(value) vs value.toString()
...me, and actually, the String constructor called as a function (your first em>x m>ample), will at the end, call the toString method of the object passed, for em>x m>ample:
var o = { toString: function () { return "foo"; } };
String(o); // "foo"
On the other hand, if an identifier refers to null or undefined...
Which parts of Real World Haskell are now obsolete or considered bad practice?
In the chapter 19 of Real World Haskell a lot of the em>x m>amples now fail due to the change of Control.Em>x m>ception .

How do you use the Immediate Window in Visual Studio?

Finding ALL duplicate rows, including “elements with smaller subscripts”
...
duplicated has a fromLast argument. The "Em>x m>ample" section of ?duplicated shows you how to use it. Just call duplicated twice, once with fromLast=FALSE and once with fromLast=TRUE and take the rows where either are TRUE.
Some late Edit:
You didn't provide a repro...
What's best SQL datatype for storing JSON string?

Certainly NOT:
TEm>X m>T, NTEm>X m>T: those types are deprecated as of SQL Server 2005 and should not be used for new development. Use VARCHAR(MAm>X m>) or NVARCHAR(MAm>X m>) instead
IMAGE, VARBINARY(MAm>X m>) : IMAGE is deprecated just like TEm>X m>T/NTEm>X m>T, and there's r...

Time complem>x m>ity of Sieve of Eratosthenes algorithm
...imes up to n, which is O(n log log n). (See here or here.)
The "find the nem>x m>t prime number" bit is only O(n) overall, amortized — you will move ahead to find the nem>x m>t number only n times in total, not per step. So this whole part of the algorithm takes only O(n).
So using these two you get an u...
