For C shared library, you can load the dll by loadlibrary and call functions by calllib.

For C++ shared library, you need to do addpath in order to set your dll file to MATLAB's search path and you can call functions by clib.libname.funcname.

For .NET assembly, you can load the dll by NET.addAssembly and call functions by like this.
 asm = NET.addAssembly('your.dll');
 
 cls = dotNetTestClass.TestClass; % dotNetTestClass is namespace and TestClass is class in C#
 a = 1; % Input 1
 b = 2; % Input 2
 result = TestFunc(cls, a, b); % TestFunc is function name in C#
For detail, please see this document.

If the dll is created from .slx using Embedded Coder, you need to do an additional step as described in the following answer.
