How do you analyze the first 10 columns of an array (all rows) and columns 11-20, 21-30, and so on, separately?

Either reshape the array:
x = rand(20, 100);
y = reshape(x, 20, 10, 10);
m = mean(x, 2); % If you want the mean value over block of 10 columns
or use a loop:
for k = 1:10:100
a = k;
b = k + 9;
process(x(:, a:b));
end
