cart2pol

Transforms Cartesian coordinates to polar or cylindrical.

Syntax

• [theta, rho] = cart2pol(x, y)
• [theta, rho, z] = cart2pol(x, y, z)

Input argument

• x - a numeric value (double or single real): Cartesian coordinates
• y - a numeric value (double or single real): Cartesian coordinates
• z - a numeric value (double or single real): Cartesian coordinates

Output argument

• theta - a numeric value: Angular coordinate.
• rho - a numeric value: Radial coordinate.
• z - a numeric value: Elevation coordinate.

Description

cart2pol transforms Cartesian coordinates to polar or cylindrical.

Examples

x = [5 3.5355 0 -10];
y = [0 3.5355 10 0];
[theta, rho] = cart2pol(x, y)

x = [1 2.1213 0 -5];
y = [0 2.1213 4 0];
z = [7 8 9 10];
[theta, rho, el] = cart2pol(x, y, z)
