Plotting a mxn Matrix

Hi ! Everyone. I wanted to ask a simple question here that If I have to plot a matrix containing m rows and n columns and say that it contains the temperature distribution of any shape. i wanted to as that which is the best method to display such type of distributions. I use imagesc mot of the time. Any better way to do that.

Separate Question

Also lets say that the shape is irregualar like U-shaped Conductor now I have made all the temperature code in the U shaped area with the reduntant square area in between. How to show this efficiently. Figure below

That how I got it

What you show is okay.

As you are using imagesc() you might want to pass in an 'AlphaData' option with a double precision matrix that is 0 inside the open area (no data) and 1 in the U (data). AlphaData 0 indicates that the area is to be transparent, showing through whatever is underneath (such as the background of the axes.)
