DLL from MinGW has different architecture than the host

I am using MinGW to create a shared library, so the shared library is created with extension DLL, and I can use it to link programs in Windows.

But when I try to load the library using loadlibrary, I get a message "has different architecture than the host". Thus, the library cannot be loaded.

If my library was crerated using MinGW and that is teh compiler used by MATLAB why it cannot load the library?

This is a limitation of loadlibrary function.

loadlibrary does not support libraries generated by the MATLAB Compiler SDK™ product.

Actually it can be done. But you need to use the Matlab MinGW64 compiler. I did it with a simple library that adds two numbers.
