...共轭元素替换矩阵的转置。 关于逆矩阵的更多信息 矩阵的逆矩阵被定义为一个矩阵,它在相乘时给出单位矩阵。因此,根据定义,如果AB=BA=I,那么B是A的逆矩阵,A是B的逆矩阵。因此,如果我们考虑B=A-1,那么AA-1=A-1A=I 矩阵可逆...
...偏导数是一类特殊的方向导数。 Derivative of a vector-valued function f can be defined as the limit wherever it exists finitely. As mentioned before, this gives us the rate of increase of the function f along the direction of the vector u. In the case of a single-valued function, this r...

...问题就会变得更容易了。 什么是拉普拉斯变换? Given a function f (t) of a real variable t, its Laplace transform is defined by the integral (whenever it exists), which is a function of a complex variable s. It is usually denoted by L {f (t)}. The inverse Laplace transform of a fu...
...ation command, I have the following question. How do I define a PowerShell function that requires elevation, as in activating a UAC prompt on my Windows 8.1 Pro, 64-bit system? For example, say I run the following function: With the following results: To be completely clear, if I run PowerShell as...
...? 答案 超级用户贡献者mtone为我们提供了答案: If a VBA function is called from several formulas or if your script generates or forces the recalculation of several formulas, then this should definitely make use of the multi-threaded calculation feature in Microsoft Excel. Respectiv...
...行。然后,将从名为Scope的文件运行以下脚本-演示.ps1: Function FunctionScope { 'Changing $MyVar with a function.' $MyVar = 'I got set by a function!' "MyVar says $MyVar" } '' 'Checking current value of $MyVar.' "MyVar sa...
...之前,我假设您已经下载并安装了它。 I’ve created a **all function that you can add to a script which will do the hard work of finding and toggling the window. All you have to do is assign the hotkeys you want at the top of the script. 您需要做的第一件事是下载脚本并...
...函数可以有垂直和水平渐近线。 一。考虑函数f(x)=1/x Function f(x)=1/x has both vertical and horizontal asymptotes. To find the horizontal asymptote find the limits at infinity. limx→=+∞ 1/x=0+ and limx→=-∞ 1/x =0–When x→+∞, function approaches 0 from the posit...
