math-cn

Math extension to work on complex numbers.

For example to perform:

$$ \begin{array}{l} z_1 = 1+2i \\ z_2 = 3+4i \\ s = z_1 + z_2 = 4+6i \end{array} $$

write:

const z1 = [1,2];
const z2 = [3,4];

const s = Math.cn.add(z1,z2);
// [4,6]

Methods

A complex number is expected to be an array of form [re,im].

• mod(z) - returns the modulus of a number
• arg(z) - returns the argument of a number
• conjugate(z) - returns the conjugate of a number
• add(z1,z2) - performs addition of numbers
• sub(z1,z2) - performs subtraction of numbers
• mul(z1,z2) - performs multiplication of numbers
• div(z1,z2) - performs division of numbers
• pow(z,n) - returns the n-th power of a number
• roots(z,n) - returns the n-th roots of a number
• cis(r,phi) - returns a complex number [re,im] defined by modulus (r) and argument (phi)
