You can also test a variable to find a match on specific values. The following code shows one example where you test a value against all possible values declared in an enumeration: C# publicStatePerformOperation(Operation command)=> commandswitch{ Operation.SystemTest => RunDiagnostics(), Operatio...
Moreover, combined with the treatment for the boolean expressions, the scope of pattern variables is robust against code refactorings that exploit the familar boolean logical equivalences. For example, the previous code can be rewritten as: if (!(e instanceof String s)) { ... // s not in...
The following code checks arrays for integer values in expected positions: C# Copy int[] empty = []; int[] one = [1]; int[] odd = [1, 3, 5]; int[] even = [2, 4, 6]; int[] fib = [1, 1, 2, 3, 5]; Console.WriteLine(odd is [1, _, 2, ..]); // false ...
C# 7 finally introduced a long-awaited feature called “pattern matching”. If you’re familiar with functional languages like F# you may be slightly disappointed with this feature in its current state, but even today it can simplify your code in a variety of different scenarios. Every new fea...

嵌入式代码构造(?{code})和(??{code})、 嵌入式注释语法(?#comment)和 预处理操作\l\u、\L和\U。 此类支持但 Perl 不支持的构造: Possessive 数量词,它可以尽可能多地进行匹配,即使这样做导致所有匹配都成功时也如此。 字符类并集和交集,如上文所述。

To do so, on your MATLAB path, save the following code to a file named ellipsetilt.m. function [c,ceq] = ellipsetilt(x) ceq = []; c = x(1)*x(2)/2 + (x(1)+2)^2 + (x(2)-2)^2/2 - 2; Start patternsearch from the initial point [-2,-2]. Get x0 = [-2,-...
