Plot a table into 16 rectangles

Hi,

I am trying to plot this table (below) as 16 rectangles of equal size and each of these rectangles FaceColor being the value within the table

3.046095 ¦ 3.065321 ¦ 2.897449 ¦ 2.766175

2.947777 ¦ 3.005672 ¦ 2.878440 ¦ 2.716963

2.865979 ¦ 2.911387 ¦ 2.780432 ¦ 2.529457

2.797027 ¦ 2.761119 ¦ 2.577187 ¦ 2.360562

I had a look through http://stackoverflow.com/questions/16114573/plotting-a-rectangle-with-colour-representing-a-value-in-matlab, but I couldn't find how to use the faceColor and match it with an actual value.

I look for surf and contourf, but neither of them are suitable since they turn this table into 9 rectangles instead of 16.

I'll appreciate any help pointing me in the right direction :):):)

If you want to do it as a proper 3D plot, you're probably best off by building up patch objects.

e.g.

 patch([0 1 1 0],[1 1 0 0],[3.046095  3.046095  3.046095  3.046095],3.046095./max_of_the_table)

If you want just an image. imagesc should do the job. "image" will do it with some thought.

Actually I only want it as a 2D plot, not 3D plot.

Then try the imagesc function, like I suggested.
