How to create a text file in a specific form of data arrangement

Hello, I'd like to know how to create a text file that can be used as input to another program

For example, this is my data

x = [1 2 3 4 5];

q = [6 7 8 9 10];

The text file should be in the form like this

x 5

1 2 3 4 5

Data

6 7 8 9 10

All data should be displayed in a row not column form.

The headers are x 5 and Data

*5 is the data count

I tried using frprint and read all the documents related but I still don't know how to do it.

I'm very new to MATLAB. Any help would be greatly appreciated.

x = [1 2 3 4 5];

q = [6 7 8 9 10];

fid = fopen('data.txt','w') ;

fprintf(fid,'%s %d\n','x',length(x)) ;
fprintf(fid,'\n') ;
fprintf(fid,[repmat('%f ',1,length(x)),'\n'],x') ;
fprintf(fid,'\n') ;
fprintf(fid,'%s \n','Data') ;
fprintf(fid,'\n') ;
fprintf(fid,[repmat('%f ',1,length(q)),'\n'],q') ;

fclose(fid) ;
