matlab Rodrigues

Rodrigues' rotation formula, also known as the Rodrigues' rotation formula, is a mathematical formula used to calculate the 3D rotation matrix from an axis-angle representation. This formula is commonly used in computer graphics and computer vision applications.

In MATLAB, you can use the `rodrigues` function to apply the Rodrigues' rotation formula. The syntax for using this function is as follows:

R = rodrigues(w)

where `w` is a 3-element vector representing the rotation axis and angle. The output `R` is a 3x3 rotation matrix.

Here's an example usage:

% Define axis and angle
axis = [0.5774, 0.5774, 0.5774]; % normalized axis
angle = pi/4; % angle in radians

% Compute rotation matrix using Rodrigues' formula
R = rodrigues(axis*angle);

% Display the rotation matrix
disp(R);

Please note that the `rodrigues` function is not built-in to MATLAB, but you can find implementations of it in various MATLAB libraries or create your own implementation based on the formula.
