You can receive data from com port (Serially). Use This Command
Ser_Obj = serial(); % Serial Communication Object (Default Setting) %
for i = 1 : 1024 % for 0 - 1023 decimal received %
fscanf (Ser_Obj); % for receiving data %
end
The formt of fscanf is given by (you can see on Matlab help)
A = fscanf(fid,format)
[A,count] = fscanf(fid,format,size)
and if you want to do in GUI then Make a GUI file and take a push button and write this code in push button. Doing this when you press the push button then you receive data.

I think the decimal data is what is in the range 0-1023, not 1024 items of data.
