Raspberry pi connection error

I am trying to connect MATLAB to the Raspberry pi by with following command, but this error happens.
I choose "Customize the existing ..." when I select Linux operating system, bacause it didn't work well with the other way(tried all network selection). And all peripheral modules are enabled now.
How can I solve this?
>> rpi = raspi('xxx.xxx.xxx.xxx', 'pi', 'xxx');

the pointer type conflict for sockRecv is the only thing I see that would concern me. There are a series of warnings based on the theoretical difference between char and unsigned char but I have not seen any os use signed char since SunOS (before Solaris even).
