Hi all,
I have problem with converting m-file in Matlab to dll file to be used in Labview. I used MCC to create dll from which Labview cannot find inputs and outputs. And is there any way to convert m-file to be used in Labview except using Matlab node due to its slow calculation speed? Thank you in advance.

I'm not sure exactly what kind of interface LabVIEW requires, but this is how you need to interface with a DLL generated using MATLAB Compiler. Note that you will also need to install the MATLAB Compiler Runtime (MCR) on the machine that the DLL is being deployed upon.
I wonder of what you actually need is a standalone DLL (independent of the MCR) - in that case using MATLAB Coder might be the better option.

Jong: How does LabVIEW "search" for interface exactly? Does it use the DLL header? Perhaps you might be able to ask NI's Technical Support team?

I've put together an example on how to do this from start to finish:

I'm up against the same issue. I've created both C shared libraries and C++ shared libraries, but cannot use in LabVIEW. How is the MATLAB runtime invoked, initialized?

GET A DLL FROM MATLAB:
mcc -v -B csharedlib:sumarray sumarray.m
create a scriptWrapper.c,scriptWrapper.h,scriptWrapper.def file[attached]
Now run below
mbuild -v sumarrayWrapper.c sumarray.lib LINKFLAGS="$LINKFLAGS /DLL /DEF:sumarrayWrapper.def" LDEXT=".dll" CMDLINE250="mt -outputresource:$EXE';'2 -manifest $MANIFEST"
now load this new scriptwrapper.dll in labview via import option, and add your old script.dll to this lvlib in labview
Always run loadFunction.vi before using your mainfunction.vi

Dear Shubham Kumar Gupta:
I tested the code for preparing matlab DLL for labview, I have some questions, maybe you can help me. How can I create the Wrapper.c file when you have multiple inputs and multiple outputs?
