how to repeat looping the matrix

Hi I have matrix 401*100 I want to make a code that can take the first row in matrix until reach to the end of row and start again from same matrix and take first row to the end of row and do this 451 times or until specific conditions . i want to use for adaptive linear neuron (adaline) for near infrared data

A = rand(451,100) ;

[nx,ny] = size(A) ;
for i = 1:nx    % loop for nx times 
    for j = 1:nx    % loop to pick row 
        A(j,:)
    end
end

But I am surprised....why?
