Altering axes in subplot

I have a matrix whose values change with each iteration, and this matrix I plot. A minimal example is the following

    figure(1)
     a=ones(11, 11);
     for i=1:20
         a(2, 3) = 1+a(2, 3);
         a(1, 4) = 1+a(1, 4);

         subplot(1,2,1), imagesc(a)
         subplot(1,2,2), imagesc(a)

         pause(0.1)
     end

I would like to do the following:

1. On the plot to the left (they are identical only in this example..) I would like the x-axis to start at 0. If i use `xlim([0 11])` the first column (belonging to 0) is just white. Is there a way to circumvent this?

2. I would like for the left y-axis to run from `-5..5`.

Is there a way to achieve this? Thanks in advance.

The question is not clear yet. What do you want to appear instead of the white column? What about ylim([-5 5])?

Try this:

    function test()   
        figure(1)
        a = zeros(11,11)+32;
        a([1,1,11,11],[1,11,1,11]) = 1;
        ax1 = subplot(1,2,1);  
        ax2 = subplot(1,2,2); 
        for i=1:20
            a(1, 1) = 1+a(1, 1);
            a(1,11) = 2+a(1,11);
            a(11,1) = 3+a(11,1);
            a(11,11)= 1+a(11,11);
            image( a, 'Parent', ax1 )
            image( a, 'Parent', ax2 )
            set( ax1, 'XLim', [ 0.5, 11.5 ] )
            set( ax1, 'YLim', [ 0.5, 11.5 ] )
            set( ax2, 'XLim', [ 0.5, 11.5 ] )
            set( ax2, 'YLim', [ 0.5, 11.5 ] )
            pause( 0.1 )
        end
    end
