Use vs2017 and matlab2017a solution platform is x64, MCR and environment variables are configured,
Wrote a simple. M file mapping, according to the online tutorial generated DLL files for reference, and the figure nested in c # form a panel control, according to
But running figure image has not been displayed, the form has become very small, there is no error, set a breakpoint found matlab functions can be normal call,
Stick procedures below, bosses answer
