This error occurs when the shared library has dependencies which MATLAB® cannot find.
On Windows® systems, to find library dependencies, use the
third-party product Dependency Walker. Dependency Walker is a free
utility that scans Windows modules and builds a hierarchical
tree diagram of all dependent modules. For each module found, it lists
all the functions exported by that module, and which of those functions
are called by other modules. Download the Dependency Walker utility
from the website
information on using the Dependency Walker.
