I'm not sure why you would want to read in numerical data as strings.
You can read in the data in your files using (assuming for example your file is called myfile.csv)
A = readmatrix('myfile.csv','Delimiter',' ')
note that you seem to have two spaces between your values so it is ' ', not ' ' as the delimiter.
If you really want them to be strings, you can alway change them into strings after you read them in as numbers, using for instance
If for some reason readmatrix is confused about some of the initial header lines (the ones you shouw starting with #, if you know how many header lines you can also specify that for example, for 3 header lines as you show in your listing
A = readmatrix('myfile.csv','Delimiter,' ',NumHeaderLines',3)
