Description

The Mach Number block computes Mach number.

Mach number is defined as

$$Mach=\frac{\sqrt{V\cdot V}}{a}$$

where α is speed of sound and V is velocity vector.

Inputs and Outputs

Input	Dimension Type	Description
First	m-by-3	Contains the velocity vector.
Second	1-by-1	Contains the speed of sound.

Output	Dimension Type	Description
First	m-by-1	Contains the Mach number.

Examples
