This should help you get started. I just added some lines to your code to make it look more like the old one

hdl = surf(B);
shading interp
xlabel('row')
ylabel('column')
% added stuff
colormap(jet) % old colormap
colormap(flipud(colormap)) % invert colormap (following Walters Remark)
hdl.EdgeColor = 'k' % black lines

If you are using R2014b or newer, then

cb = colorbar();
cb.Ruler.Scale = 'log';

You can use two linked axes with different colormaps. Example:

% Axes
ax(1)=axes('color','none','xcolor','none','ycolor','none');hold on
ax(2)=axes('color','none','xcolor','none','ycolor','none','ydir','reverse');hold on
linkaxes(ax,'xy')
axis([-3 3 -3 3])
% Contour data
[X,Y,Z] = peaks;
% Image
axes(ax(2))
I = imread('cameraman.tif');
imagesc(I,'XData',[min(X(:)) max(X(:))],'YData',[min(Y(:)) max(Y(:))]);
colormap(ax(2),'gray')
% Contour
axes(ax(1))
h = contour(X,Y,peaks);hold on
colormap(ax(1),'parula')

Just make sure the axes have the same position. If you create a colorbar "outside" of the axes area, then one axis will shrink. Usually I just create the colorbar "inside" and then move it outside by adapting its position properties.
