Purpose Imaginary unit<br />

Syntax i<br />

a+bi<br />

x+i*y<br />

Description As the basic imaginary unit sqrt(-1), i is used to enter complex numbers.<br />

Since i is a function, it can be overridden and used as a variable. This permits<br />

you to use i as an index in for loops, etc.<br />

If desired, use the character i without a multiplication sign as a suffix in<br />

forming a complex numerical constant.<br />

You can also use the character j as the imaginary unit.<br />

Examples Z = 2+3i<br />

Z = x+i*y<br />

Z = r*exp(i*theta)<br />

See Also conj, imag, j, real<br />
