Hello,
I am working on a project, where I have to plot some COMSOL images. I choose to get data from COMSOL and plot it through MATLAB, as i have many images. Its a 2D plot.
I am attaching both the images. Problem is I get a very smooth image from COMSOL but when plotting it through MATLAB give me not so good image.
I tried using some noise filter , but could not get a good reslt.
Can some one suggest me, how can i smoothen the image?
First image is COMSOL generated and second is MATLAB plotted.
Thanks Anushka

You are just using a colorbar with not many colors (64) so it looks posterized. Use a colormap with higher precision/more colors
colormap(jet(256));
