I have a script that will generate a 12×12 matrix of ones and zeros. When I create an image from this the default colours are yellow for one and blue for zero. I want to change this to white for zero and red for one.
Can anyone help me?
Thanks,
Joe
m = zeros(12, 12);numIterations = 1800;row = ones(1, numIterations);col = ones(1, numIterations);m(row(1), col(1)) = 1;imagesc(m);axis('on', 'image');percentage = 0.40; % 20% of time will be the same
for k = 2 : numIterations if rand(1) < percentage % 20% of the time it will stay in the same place.
row(k) = row(k-1); col(k) = col(k-1); else % 80% of the time it will select a new place.
% First get a tentative new location.
row(k) = row(k-1) + randi([-1,1], 1); col(k) = col(k-1) + randi([-1,1], 1); while row(k) == row(k-1) && col(k) == col(k-1) || row(k) <= 0 || row(k) > size(m, 1) || col(k) <= 0 || col(k) > size(m, 2) % Get a new location.
row(k) = row(k-1) + randi([-1,1], 1); col(k) = col(k-1) + randi([-1,1], 1); while row(k) <= 0 || row(k) > size(m, 1) row(k) = row(k-1) + randi([-1,1], 1); end while col(k) <= 0 || col(k) > size(m, 2) col(k) = col(k-1) + randi([-1,1], 1); end end end m(row(k-1), col(k-1)) = 0; % Clear old location
m(row(k), col(k)) = 1; % Set new location
imagesc(m); grid on; caption = sprintf('At Iteration %d, Row = %d, Column = %d', k, row(k), col(k)); title(caption, 'FontSize', 15); drawnow; pause(0.8)end
