Powershell provides a lot of built-in support for common parameter scenarios, including mandatory parameters, optional parameters, “switch” (aka flag) parameters, and “parameter sets.” By default, all parameters are optional. The most basic approach is to simply check each one for $null, then implement whatever logic you want from there. This is basically what you have … Read more
For newer releases of Matlab (eg 2007 or 2008) you could use the built in functions: mlint dependency report and coverage report Another option is to use Matlab’s profiler. The command is profile, it can also be used to track dependencies. To use profile, you could do >> profile on % turn profiling on >> … Read more
primes, in your code, is not a function, but a constant, in haskellspeak known as a CAF. If it took a parameter (say, ()), you would get two different versions of the same list back if calling it twice, but as it is a CAF, you get the exact same list back both times; As … Read more
In PowerShell functions are not overloaded. The last definition overrides the previous in the same scope or hides the previous in a parent scope. Thus, you should create a single function and provide a way to distinguish its call mode by arguments. In V2 you may use an advanced function, see help about_Functions_Advanced_Parameters and avoid … Read more
What you are asking for does not exist, you appear to be asking: Can I reference a companion object method of a superclass from a class reference of its descendants or maybe you are asking: Can I reference a static member of a superclass from a reference of its descendants. The answer for both is … Read more
To return a value from a VBScript function, assign the value to the name of the function, like this: Function getNumber getNumber = “423” End Function
Covariance and contravariance are qualities of the class not qualities of the parameters. (They are qualities that depend on the parameters, but they make statements about the class.) So, Function1[-A,+B] means that a function that takes superclasses of A can be viewed as a subclass of the original function. Let’s see this in practice: class … Read more
Your function has a couple of smallint parameters. But in the call, you are using numeric literals that are presumed to be type integer. A string literal or string constant (‘123’) is not typed immediately. It remains type “unknown” until assigned or cast explicitly. However, a numeric literal or numeric constant is typed immediately. The … Read more
With PostgreSQL 9.4 there is native support for percentiles now, implemented in Ordered-Set Aggregate Functions: percentile_cont(fraction) WITHIN GROUP (ORDER BY sort_expression) continuous percentile: returns a value corresponding to the specified fraction in the ordering, interpolating between adjacent input items if needed percentile_cont(fractions) WITHIN GROUP (ORDER BY sort_expression) multiple continuous percentile: returns an array of results … Read more
You can call a Javascript function with any number of parameters, regardless of the function’s definition. Any named parameters that weren’t passed will be undefined. Extra parameters can be accessed through the arguments array-like object.
