Adding the individual columns of a matrix.

I have a huge matrix file containing some 1.5 million rows and 6000 columns. The matrix looks something like this:

I want to add all the numbers in the columns of this matrix and display the result to my stdout. This means that the numbers in the first column are:

When I add all of them up the result is 15 and in this way the sum of numbers present in the second column is 19 and third is 23. Hence my output should look like this:

I can add the numbers in the first column like this:

But don't know how to do it for the entire matrix of 6000 columns.
