i

Imaginary unit

Syntax

• i
  a+bi
  x+i*y
  

Description

As 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.

Examples

• Z = 2+3i
  Z = x+i*y
  Z = r*exp(i*theta)
