sqrt

Square root.

Syntax

• R = sqrt(M)

Input argument

• M - a variable

Output argument

• R - result of sqrt: square root.

Description

sqrt computes the square root.

If input argument is a complex number or negative, sqrt(z) computes: sqrt(r) * (cos(phi/2) + sin(phi/2) * i) with

r = sqrt((real(z) * real(z)) + (imag(z) * imag(z))) and phi = atan2(imag(z), real(z))

Example

x = -3:3;
r = sqrt(x)
