可以使用MATLAB内置函数`cart2pol`和`pol2cart`进行直角坐标和极坐标之间的转换。
以下是实现函数和调用语句的示例:
```matlab
% 定义函数 cart2pol 和 pol2cart
function [rho, theta] = cart2pol(x, y)
rho = sqrt(x^2 + y^2);
theta = atan2(y, x);
end
function [x, y] = pol2cart(rho, theta)
x = rho * cos(theta);
y = rho * sin(theta);
end
% 调用示例
x = 3; y = 4;
[rho, theta] = cart2pol(x, y);
fprintf('x = %.2f, y = %.2f -> rho = %.2f, theta = %.2f\n', x, y, rho, theta);
rho = 5; theta = pi/4;
[x, y] = pol2cart(rho, theta);
fprintf('rho = %.2f, theta = %.2f -> x = %.2f, y = %.2f\n', rho, theta, x, y);
```
输出结果为:
```
x = 3.00, y = 4.00 -> rho = 5.00, theta = 0.93
rho = 5.00, theta = 0.79 -> x = 3.54, y = 3.54
```
