AWR1443BOOST: How can I demo capture_demo.m script in matlab ?

Part Number:AWR1443BOOST

Hello 

      I try to take raw data from the capture demo. And I follow the users' guide "mmwave_sdk_user_guide" . I have already get the .dat file. But I don' know how to implement it on Matlab.

Here is my step

1. I take the .bat file and capture_demo.m file in the same folder 

2. Open matlab and in command window enter    fileName = "ccs_demo.dat"
3. Run the capture_demo.m

And it has error say

Not enough input arguments.

Error in capture_demo (line 86)
datFile = strfind(fileName,'.dat');

Do I ave wrong step ? Thank you  

Sincerely Wendy
