Write to a .txt file

Hello, I have to write a code that will do what the following question asks. I am very confused on how to do this.

'You will want to add up all of the vectors in the file called "Random_Data.txt", but in addition, you want to save all of the intermediate results. For example, once you add up the first two vectors, write the results into another text file called "Results.txt". The next line should have the intermediate answer of adding the previous result to the third vector, etc... Your Results.txt should contain vector_count - 1 vectors with the final vector being the final answer for adding all of the vectors up in the Random_Data.txt file.

Example:

Original File:

1 1 1 1 1
1 1 1 1 1
1 1 1 1 1
1 1 1 1 1

Results.txt

2 2 2 2 2
3 3 3 3 3
4 4 4 4 4

any help is much appreciated!

The quick way is to use cumsum() and write out the 2nd row to the end row.

i tried this code and it did not work.

B = cumsum(my_ans)
C = B([2:end],:)
fprintf(fileID, '%d/t%d/t%d/t%d/t%d/n', C')
