showimg.m

  Usage h=showimg(x,y,A)

  Very similar to imshow, but makes it easier to pass pixel coordinates.

  Example usage:
    A = imread('cameraman.tif');
    A(1,1,3)=0; %set the green and blue channels to all zeros. 
    x = (1:size(A,2))*10+100;
    y = (size(A,1):-1:1)*10+100;
    showimg(x,y,A);
