Need a explanation for the matlab code snippet
- by Mask
%# load a grayscale image
img = imread('coins.png');
%# display the image
figure
imshow(img,[]);
%# false-color
colormap('hot')
The above code is from here:

But I don't understand how figure(What's the difference with/without it?) and colormap(How does it affect the already shown img?) work?
