pol2cart

Purpose

Transform polar coordinates to Cartesian.

Synopsis

[x,y] = pol2cart(theta,rho)
[x,y,z] = pol2cart(theta,rho,z)

Description

[x,y] = pol2cart(theta,rho) transforms data stored in polar coordinates to Cartesian, or xy, coordinates. theta and rho must be the same size. theta is in radians.

[x,y,z] = pol2cart(theta,rho,z) transforms data stored in cylindrical coordinates to Cartesian coordinates. theta, rho, and z must all be the same size.

Example

theta = 0:.01:2*pi;
rho = sin(2*theta).*cos(2*theta);
polar(theta,rho)
          


          
[x,y] = pol2cart(theta,rho);
plot(x,y)
