Pipe program output to CSV file

I am currently programming benchmarks for my thesis. Until now I copied the output of my program to a calc tool and generated the plots for it.

Now I would like to save some time and write a bash cript which will run my program 15 times and write the results in a CSV file.

Output looks like this

2.400376 
12.917778 
16.106343 
15.971737 
17.167294 
17.075996 
17.057590 
17.113480 
17.074406 
17.064394 

2.718820 
11.456631 
16.918703 
17.725768 
17.833584 
17.808625 
17.883213 
17.889387 
17.899784 
17.894960

The output of the following loop should be saved in the next column of the CSV

Any suggestions how to do this? I have some basic knowlegde of bash scripting but this is beyond my possibilities currently

Thanks in advance

Run your program 15 times:

for i in {1..15}; do
  myprogram >> ${i}.txt
done

Join all the outputs together in one file, specifying a comma as the delimiter:

paste -d ',' {1..15}.txt > output.csv

If you are not using bash, you could replace the {1..15} construct with $(seq 1 15).
