You can check whether a value is real or complex usingisreal. To get moduli or magnitude of complex number you can useabs. Read aboutisreal,abs.https://in.mathworks.com/help/matlab/complex-numbers.html 참고
The absolute value (or modulus) of a real number is the corresponding nonnegative value that disregards the sign. For a real value, a, the absolute value is: a, if a is greater than or equal to zero -a, if a is less than zero abs(-0) returns 0. ...

A complex number z has a modulus or absolute value in [0,infty), which Matlab computes with ABS(z), and an argument in (-pi,pi], which Matlab computes with ANGLE(z). For example: angle(1) ans = 0 angle(-1) ans = 3.141592653589793 angle(-1-.01i) ans = -...
By simply multiplying both terms in Eq. (2) by the modulus r, and using Eq. (1), the following equation is obtained: (4)r·eiθ=r(cosθ+i·sinθ) But taking a look at Fig. 1, it can be seen that any number z fulfilling (1) also fulfills (4). Therefore, there are ...
In calculus, the exponential function is introduced together with the sine and cosine functions. Note that the modulus tells us how far we go from the origin to get a complex number in the Argand diagram. The direction of a complex number is known as argument. The Taylor series expansions ...
On the other hand using the CMA for nonconstant modulus signals such as QAM signals yields degraded performance because the CMA projects all signals points onto a single modulus. In order to improve the performance of CMA for QAM signals a number of modified methods have been introduced such ...
Here,Modis performing the modulus operation. After calculating each\(H_{i}\), updateDby dividing it by 16 and taking the floor value of the result:\(D=D/16\). Repeat these steps until\(D_{i}\)becomes zero. The hexadecimal numberHis then represented by the string of digits obtained:\...
The absolute value of a complex numberz=x+y*iis the value∣z∣=√x2+y2. Here,xandyare real numbers. The absolute value of a complex number is also called a complex modulus. Tips Callingabsfor a number that is not a symbolic object invokes the MATLAB®absfunction. ...
developed a calculation program via Matlab software and put forward a method for predicting and matching the stiffness of composite leaf springs. They probed into the influences of the layup angle, the fiber volume fraction, and the number of layers on the stiffness. Chen Qian et al. [6] pr...
