Heatmap matlab

The heatmap is a way of representing the data in a 2-dim

The size of the "B" matrix matters because when you add a very large graphics object to a plot, MATLAB automatically switches the renderer over to opengl (presumably because of the better performance vs. painters or zbuffer). So, when you execute this code in R2011b, you get no exponent on the axis: ...Heatmap charts use the 256-sampling of the sky colormap by default. You can change the sampling by specifying the Colormap name-value argument. For example, create two heatmap charts in a 2-by-1 tiled chart layout. The top chart uses the default set of 256 colors, and the bottom chart uses only two colors.A Complete Guide to Heatmaps. Posted by Mike Yi. What is a heatmap?
