pol2cart

Arguments

theta

Angular coordinate relative to the X-axis. Must have the same size as rho.

rho

Radial coordinate (distance to pole). Must have the same size as theta.

z

Elevation coordinate. Must be a scalar or have the same size as theta.

XX, YY, ZZ

Cartesian coordinates.

Description

For real scalars, vectors or matrices theta and rho (polar coordinates), pol2cart(theta, rho) returns Cartesian XX and YY coordinates. For real scalars, vectors or matrices theta, rho and z (cylindrical coordinates), pol2cart(theta, rho, z) returns Cartesian XX, YY and ZZ coordinates. If z is a scalar then ZZ is expanded to the same size as theta.

Examples

theta = 0:%pi/2:%pi;
rho = [2 4 6];
[x, y] = pol2cart(theta, rho)

z = 5:7;
[XX, YY, ZZ] = pol2cart(theta, rho, z)
