MATLAB's implementation of light sources does not perform any ray tracing which is necessary to produce shadows. Light sources in MATLAB illuminate each object in the axes with respect to the object's lighting related properties only.
However, if you have the Mapping Toolbox, you may find the LOS2 and VIEWSHED functions useful:
