Description

The Calculate Range block computes the range between two vehicles. The equation used for the range calculation is

$$Range=\sqrt{{(x_1-x_2)}^2+{(y_1-y_2)}^2+{(z_1-z_2)}^2}$$

Ports

Input

x1 — Vehicle 1 position

3-element vector

Contains the (x, y, and z) position of vehicle 1, specified as a three-element vector. These values of the double data type.

Data Types: double

x2 — Vehicle 2 position

3-element vector

The (x, y, and z) position of vehicle 2, specified as a three-element vector. These values are of the double data type.

Data Types: double

Output

R2-1 — Range

scalar

Range from vehicle 2 and vehicle 1, returned as a scalar of double data type. The calculated range is the magnitude of the distance, but not the direction. It is always positive or zero.

Data Types: double
