% Wrtie a binary file
fid = fopen('new.bin','w');
A= [1 2 3 4];
fwrite(fid,A);
fclose(fid);
% Read the file created
fid = fopen('new.bin','r') ;
A = fread(fileID) ;
fclose(fid)
A
It is working fine. You are writing data to a binary file, use fread to read the file created.
Note: You asked many questions and accepted no answer so far. You must acknowledge the people who spent time to answer your queries. You have to accept the answer.

As you know the format while you have written the file. You can read the file as below:
fid = fopen('new.bin','r') ;
A = fread(fileID,[1 4]) ;
fclose(fid) ;
A
I suggest you to read documentation part of fread.
