How do I create smooth color plots in Matlab?
Here is where I am at now. I use the imagesc function and I send you two images. One of them is smoother and better looking and that is because I used denser meshgrid to compute the function. But still, it is discrete looking. How do I make it smooth?
Thank you

Specify an m-by-n matrix of colormap indices, where [m,n] = size(X) . Specify one color per vertex. Create matrices x , y , and c . Then plot the filled region with fill color interpolated from vertex colors c .
The shading function controls the color shading of surface and patch graphics objects. shading flat each mesh line segment and face has a constant color determined by the color value at the endpoint of the segment or the corner of the face that has the smallest index or indices.
Sounds like you need a colormap with more gradation. All the colormap generators accept an argument describing the number of discrete colors to include. Try increasing that number; I think the default is something like 64. For example:
colormap(jet(4096))
You can increase the number even further if you like, but eventually you'll hit the limits of 24-bit color space.
Incidentally, the human eye is most sensitive to color gradations in blue hues, so another thing you could do is choose an alternate colormap.
