In a complex number {eq}\displaystyle{z=a+bi} {/eq}, {eq}a {/eq} is called the real part and {eq}b {/eq} is called the imaginary part and are referred to as {eq}\Re{(z)} {/eq} or {eq}\operatorname{Re}(z) {/eq} or {eq}\mathfrak{Re}(z) {/eq}, and {eq}\Im...
In the previous chapter, we described some stories about a new element (number)i, called theimaginary unit, with the propertyi2= 1. It is also often written asi=1. A simple addition of this single element to the set of real numbers expands this set, as well as our ability to solve ...

And that agrees nicely with the definition that i2 = −1So it all works wonderfully!Learn more at Complex Number Multiplication.ConjugatesWe will need to use conjugates in a minute!A conjugate is where we change the sign in the middle like this:...

The IMABS function calculates the modulus of a complex number, IMABS probably stands for imaginary absolute. The absolute value is the same as the modulus.The modulus of a complex number is the distance of the complex number from the origin in the complex plane. It is the square root of ...
who had or had been approved for an NSSFC project or NSSFC projects. Although the number of NSSFC applicants is much greater than the number of “winning bidders”, we consider only these winners because they are more likely to share the “best” solutions in funding applications. Finally, 12...
z) agrees with the definition of ∂zf. However, Wirtinger derivatives ∂zf and ∂z∗f might exist even when the Cauchy-Riemann conditions do not hold. For example, for f = |z|2 we have ∂zf = z* and ∂z∗f...
Based on the definition in equation (1), MSAs with a more diverse set of sequence pairs with sequence identity <0.8 have the term \({\sum }_{m=1,m\ne n}^{N}I\left[{S}_{m,n}\ge 0.8\right]\) closer to 0, and thus result in a higher Neff value given the same number of ...
The following definition is needed. Let f be a function defined in the unit disc \mathbb D, with boundary circle C. A point w on C is said to be regular for f if there is an open neighborhood U of w and an analytic function g on U, so that f = g on \mathbb{D}\cap U. A...
