"虚数"是个多义词,它可以指虚数(数学用语),虚数(汉语词语)。
...表示余弦波的不同频率幅度值:Re X[],另一种是表示正弦波的不同频率幅度值:Im X[],Re是实数(Real)的意思,Im是虚数(Imaginary)的意思,采用复数的表示方法把正余弦波组合起来进行表示,但这里我们不考虑复数的其它作用,只记住是一种组合方法而已,目的是为...

例如,此方法可以轻易地支持虚数。
For example, this method could easily support imaginary Numbers.
如果这当中有一个负数,乘积就会变成负的,如果你对一个负数开根号,你就会得到一个虚数。
If you had one negative number in it, then the product would be a negative number and, if you took a root of that, then you might get an imaginary number.
单复变量包含实数和虚数两部分,针对两个实值函数n(x) 和 v(x)的表达式为:b(x) = n(x) + iv(x)。
fullprof A complex variable has real and imaginary parts written in the form b(x) = n(x) + iv(x) for two real-valued functions n(x) and v(x)
So that's the second thing I've just highlighted here, is that I now have the ability to check whether it does the right thing.
你知道的,一个虚数,但是返回虚数就没有什么价值了,那么这是我想要强调的第二件事情。
