euler angles to quaternions in matlab

To convert Euler angles to quaternions in MATLAB, you can use the built-in function eul2quat. This function takes the Euler angles as input and returns the corresponding quaternion.

Here is an example of how to convert Euler angles to quaternions in MATLAB:

main.m
% Define the Euler angles in radians
pitch = pi/4;     % Rotation around x-axis
yaw = pi/3;       % Rotation around y-axis
roll = pi/6;      % Rotation around z-axis

% Convert Euler angles to quaternion
euler_angles = [pitch, yaw, roll];
quaternion = eul2quat(euler_angles);

% Display the resulting quaternion
disp('Quaternion:');
disp(quaternion);

In this example, pitch, yaw, and roll are the Euler angles defined in radians. The eul2quat function is then used to convert the Euler angles to a quaternion. The resulting quaternion is displayed using the disp function.

Please note that the order of the Euler angles matters. The default order used by eul2quat is ZYX, where Z represents the rotation around the z-axis, Y represents the rotation around the y-axis, and X represents the rotation around the x-axis. If you have a different order of rotations, you can use the eul2quat function with the optional argument specifying the order.
