hii everybody i want to read data from analog input and display it on scope..... ? on connect to target i get this error
Could not execute target data map file
'untitled_rtt\untitled_targ_data_map' or it does not exist.
Stop the target, delete the untitled executable, rebuild the code, and
try again. Note that execution of external mode requires the build
directory to be present
please suggest me possible settings

External mode is not supported by Arduino Uno - http://www.mathworks.com/hardware-support/arduino-simulink.html
In this link you can see that interactive tuning and monitoring is not supported for Uno boards. One suggestion is to create a Simulink model that transmits the information you need serially and then use MATLAB serial commands to bring in the information to MATLAB (I understand it is a bad alternative and I apologize for the same).

The error message sounds clear. Did you try to follow the given instructions? If so, what did you observe? Please add the relevant part of the code, such that we have a chance to see, what's going on.

It is supported by the Mega 2560 and by the Due; see http://www.mathworks.com/help/supportpkg/arduino/ug/tune-and-monitor-model-running-on-arduino-mega-2560-hardware.html
The Mega ADK might also be supported; see http://www.mathworks.com/help/supportpkg/arduino/examples/communicating-with-arduino-hardware.html
I do not find any explicit statement that External Mode is not supported on other boards.
