There is nothing really called 'column matrix`. It is called just a matrix.

If you can change the program or function that was used to generate
the output above so that it writes the output in simpler way,
like this
71 7 228
70 5 228
etc...
it will be easier to read again
But in either case, you need to read the file into a matrix.
For the format you show up, you can use textscan with the
appropriate format specifier.
If the data was in the simpler form I show up, you can just
read it much easier using one command such as
importdata()
