MATLAB: How to rotate points on 3D coordinate systems

I have some points on a 3D Cartesian coordinate system. I want to transfer it form 3D coordinate system to another system which is generated from the first one by a rotation around the x, y or z-axis by (alpha) degrees counterclockwise and clockwise and calculate the position vector in the new coordinate system after the rotation. What is the best solution?

MATLAB: How to rotate points on 2D coordinate systems

Hello,

You can rotate your points with a rotation matrix:

Here's a simple implementation,

% Create rotation matrix
theta = 90; % to rotate 90 counterclockwise
R = [cosd(theta) -sind(theta); sind(theta) cosd(theta)];
% Rotate your point(s)
point = [3 5]'; % arbitrarily selected
rotpoint = R*point;

The rotpoint is the 90 degree counterclockwise rotated version of your original point.

Hope this helps!
