1j in MATLAB is a complex number with a real part of 0 and an imaginary part of 1. It can be written as 1j or 1i, depending on your preference. Complex numbers are useful for representing quantities that have both magnitude and direction, such as vectors or phasors. To create a comple...
wherexandyare real numbers, andiis the imaginary unit, which is defined asi2=-1. The numberxis the real part of the complex number, which is denoted byx=Re(z), and the numberyis the imaginary part of the complex number, which is denoted byy=Im(z). You can plot a complex number ...

Complex Numbers Complex numbers have both real and imaginary parts, where the imaginary unit is the square root of -1. sqrt(-1) To represent the imaginary part of complex numbers, use eitheriorj. c=[3+4i,4+3j;-i,10j] Indexing Every variable in MATLAB is an array that can hold many...

2) Assigning a real or complex value to a complex vector requires MATLAB to check whether the imaginary part of the complex vector is all 0's or not. If the complex vector's imaginary part is all 0's, MATLAB has to convert the complex vector...
