MATLAB: Axis control in Image plot

Question

Hi, I am trying to understand image plot. When I run this example

x = [1 5];
y = [1 5];
C = [0 2 4 6; 8 10 12 14; 16 18 20 22];
imagesc(x,y,C)

I get the figure (attached here).

In Y axis its comes in descending order. I want to get it in Ascending order. How can I control the axis range?

Answer 1

x = [1 5];
y = [1 5];
C = [0 2 4 6; 8 10 12 14; 16 18 20 22];
figure
h1 = axes ;
imagesc(x,y,C) ;
set(h1,'YDir','normal');
