Can run eval but cannot retrieve data from Matlab

[mbi2gs]

Recently, I used the NetLogo Matlab extension in my work. I can send data to Matlab and run functions (with send and eval) directly from NetLogo, but unfortunately I can't get any data directly from Matlab.

I am using Matlab R2016 and NetLogo 6.0.2. I am using matlab:send/get-double-list. I can send data to Matlab but I cannot receive anything from Matlab. I am not able to return any data type.
