i a+bi x+i*yAs the basic imaginary unit
sqrt(-1), i is used to enter complex numbers. Since i is a function, it can be overridden and used as a variable. This permits you to use i as an index in for loops, etc.
If desired, use the character i without a multiplication sign as a suffix in forming a complex numerical constant.
You can also use the character j as the imaginary unit.
Z = 2+3i Z = x+i*y Z = r*exp(i*theta)
conj Complex conjugate
imag Imaginary part of a complex number
j Imaginary unit
real Real part of complex number
