📝 Syntax

• R = sqrt(M)

📥 Input argument

• M - a variable

📤 Output argument

• R - result of sqrt: square root.

📄 Description

sqrt computes the square root.

For real positive numbers: $\sqrt{x}$

For complex numbers z = x + iy: $\sqrt{z} = \sqrt{r} e^{i\phi/2}$

where $r = |z| = \sqrt{x^2 + y^2}$

and $\phi = \arg(z) = \text{atan2}(y, x)$

💡 Example

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