Hi I'm trying to make a 2D color plot where the markers are colored based on the Z. The x-axis is atomic number, y-axis is number of protons, and Z is abundance. I don't have much coding experience. Thanks.
Have a look in the help for: pcolor and scatter HTH,

Extract Values from matrix and use them to calculate days passed
Look at matlab's datestr, datenum and datevec functions instead.

Yup, simple: M =randn(10); for i1 = 1:size(M;2) V{i1} = M(:,i1); end Then you have your vectors in the cells...

I'm trying to plot the eigenvalues of a system of equations and I'm using 'fsolve' to find the Jacobian to do this. There are 3 eigvalues, and they vary as a parameter (c) is varied. Obviously, graph is wrong (points jump about). anyone know why?
Also have a look at: <http://www.mathworks.se/matlabcentral/fileexchange/22885-eigenshuffle>

"Salt and pepper"-noise is more efficiently removed with median-type filters. Have a look at medfilt2. HTH
