hi,
*Thanks , I resolved the problem of heatmap with not default colors, but happen another problem.
My matrix data (17770*17770) with size 2 GB. what I want is show these data using heatmap This is my code:
map=[0 0.5 0.5;0.5 1 1];
h=colormap(map);
f=heatmap(data,'colormap',h);
it takes more than two hours , then get help out of memory.
Are there a way to avoid this problem?
Thanks in advance*
