If you really want to build n separate arrays, you will have to store them in a cell array, unless you want to dynamically generate variable names (which is almost never a good option). For example
n = 8 ;
m = 5 ;
c = cell(1, n) ;
for k = 1 : n
c{k} = zeros(1, m) ; % For 1xn arrays.
%c{k} = zeros(m) ; % For mxm arrays.
end
and then you can access arrays through cells form the cell array, e.g.
c{4}(3) = 9 ; % Set element 3 of array 4 to 9, if 1xm arrays.
c{4}(3,2) = 9 ; % Set element (3,2) of array 4 to 9, if mxm arrays.
However, if you are dealing with 1xn arrays, Image Analyst gave you the optimal solution.

Like one of these?
zeroArray = zeros(m, n);
oneArray = ones(m, n);
anArray = value * ones(m, n);

It's best to do it as an array, like I showed you. You don't want some number of separate arrays with different variable names. Please see the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F
