when i tipe in the code below, every second axes is shown only. this means the first point is not named at all, the second is named after the first ones name, the third is not named, the fourth has the name of the second value on that axis. I dont get why. do you? thanks a lot

[r,p] = corrcoef(x); % Compute sample correlation and p-values.

imagesc(p); % plot the matrix set(gca, 'XTick'); % center x-axis ticks on bins set(gca, 'YTick'); % center y-axis ticks on bins set(gca,'XTickLabel',{'1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19'}) set(gca,'YTickLabel',{'1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19'}) title('Correlation Matrix', 'FontSize', 12); % set title colormap('jet'); % set the colorscheme colorbar

You set the labels, but not the ticks themselves. Try something like this:

set(gca, 'XTick',1:19); 
set(gca,'XTickLabel',{'1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19'})
