You can refer to this rotatepoint function from matlab documentation for your query.
For examples and more details on the concept and math behind quaternions you can refer to this link

If the Automated Driving Toolbox is not available in your environment, please use makehgtform function to create 4-by-4 transform matrix and apply to the original point coordinates.

You can use this FEX download, which requires no toolboxes,
https://www.mathworks.com/matlabcentral/fileexchange/30864-3d-rotation-about-shifted-axis
See, in particular SYNTAX 3,
newPosition = AxelRot(oldPosition, degrees, axisDirection, axisOrigin)
