Try this:

data = csvread(filename);
csvwrite('part1.csv', data(:, 1:10));
csvwrite('part2.csv', data(:, 11:20));
csvwrite('part3.csv', data(:, 21:30));
csvwrite('part4.csv', data(:, 31:40));
csvwrite('part5.csv', data(:, 41:50));
csvwrite('part6.csv', data(:, 51:60));
csvwrite('part7.csv', data(:, 61:70));
csvwrite('part8.csv', data(:, 71:80));
csvwrite('part9.csv', data(:, 81:90));
csvwrite('part10.csv', data(:, 91:100));

Adapt as needed.
