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 any 32-bit or 64-bit Windows module 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.
