Visualise Large correlation matrix
显示 更早的评论
Hi Everybody,
Is there anyway I can create a correlation matrix heatmap in matlab?
I have a huge correlation matrix table which has been calculated in SPSS. I just need a better way of visualising this data, if anyone has any ideas that I could achieve this using matlab?
Thanks!

You can visualize a matrix by heatmap using imagesc function.
>> test = randn(100, 100);
>> figure; imagesc(test); colorbar;

Hi Peng Li,
Thanks for getting back to me.
Unfortunately when I try that with my own own data, or all I get is a colour map that looks like the graph below

better use colorbar to add a color bar so that you know the corresponding levels these colors are for. Basically this means your correlation matrix shows bigger values on row around 60. Is that expected?
