How can I convert my script into c code using matlab coder

clc;
fileID = fopen('pet_data.dat');
OneByte = fread(fileID,[5000 1]);  %first testing for first 10bytes of data 
A=uint8(OneByte);
Fs=1000;
Ts=1/Fs;
B= (0:Ts:(length(A)-1)/Fs)';
C=[B A];

When I am trying to convert the above following file into c file using matlab coder it is showing an error that it is a script and doesnot start with a function .

So i tried to give lines like these

function C = read_pet
clc;
  fileID = fopen('pet_data.dat');
  OneByte = fread(fileID,[5000 1]);  %first testing for first 10bytes of data 
  A=uint8(OneByte);
  Fs=1000;
  Ts=1/Fs;
  B= (0:Ts:(length(A)-1)/Fs)';
  C=[B A];
end

but it is not right and i have to take some input arguments to read_pet and i have to use this function somewhere. I am totally confused how can i convert this into a function in c code?

Hi Janani, what is the problem here? If you remove "clc;" and then generate the C code using

codegen read_pet -config:lib -report

then it just works for me (in R2017a)
