From my research, I've come to know anagram is not case sensitive, but this checkAnagram function is case-sensitive. it's can't pass this test case “Eleven plus two” is an anagram of “Twelve plus one”

If one uses the VisualizeError and FillColor options of RooAbsReal::plotOn(), for example like this:

using namespace RooFit;
model.plotOn(frame, VisualizeError(*r, 1), FillColor(kOrange));

You get a false warning:

WARNING:Plotting -- Fill color or style was set for plotting "model", 

IEEE 754 recommends (but does not require) a compound function, which is in the process of being standardized for C and C++; we should expose it in swift-numerics. The simplest, most literal translation of the operation into Swift would be:

extension RealFunctions {
  /// (1+x)ⁿ
  /// 
  /// Returns NaN if x < -1.
  static func compound(_ x: Self, _ n: Int) -> Self {
    // not

Start from the develop branch and add to examples/simple:

• igraph_assortativity.c, which calls the function igraph_assortativity (in /src/misc/mixing.c) with some graph and prints out the result,
• igraph_assortativity.out which contains the correct printed result.

Then, add the example to tests/CMakeLists.txt and to the docs of the function in /src/misc/mixing.c

For an example of a si
