MATLAB could not find modbus function

Hello everyone,

I have a question. When I try to use modbus function, I take that error

Could you help me please ?

Should I use different version of MATLAB ?

By the way I use MATLAB version of 2013a

m=modbus('serialrtu','COM3')
Undefined function 'modbus' for input arguments of type 'char'.
