matlab surface plot - label colorbar and change axis values

I am trying to plot a 3D surface plot in matlab with a colorbar.

I would like to know how to

  1. label the title of the colorbar

  2. change the axis tick labels

The important parts of my code are

number_panels = 1:100:500;
number_turbines = 0;
number_batteries = 0:300:1700;

for idx_number_panels = 1:length(number_panels) 

for idx_number_turbines = 1:length(number_turbines) 

    for idx_number_batteries = 1:length(number_batteries) 

        for h=2:3 %# hours

A = squeeze(total_annual_cost)
B = squeeze(total_renewables_penetration)

figure;
surface(A,B)

enter image description here I am trying to change the x and y axis ticks from the intervals of the for loop to actual numbers that represent each interval.

I can't seem to find any of the above in the documentation.

The following code shows how to change the Xticks, the Yticks and to add labels to the values of the colorbar:

clear all
close all
clc

h = surface(peaks)
colorbar('YTickLabel',...           % set labels to the colorbar
    {'Freezing','Cold','Cool','Neutral',...
     'Warm','Hot','Burning','Nuclear'})
view(-35,45)

number_panels = 0:5:50;
number_batteries = 0:15:50;

set(gca,'XTick',number_panels)      % set Xticks
set(gca,'YTick',number_batteries )  % set Yticks
grid on

enter image description here

With this code you change the first YTickLabel to set a colorbar title (well, something similar):

clear all
close all
clc

number_panels = 0:5:50;
number_batteries = 0:15:50;

h = surface(peaks);
chandle = colorbar;

current_colorbar_labels = get(chandle,'YTickLabel');
current_zticks = get(chandle,'YTick');
aux = cellstr(current_colorbar_labels);
aux{end} = 'Title';
set(chandle,'YTickLabel',aux);
view(-35,45)

set(gca,'XTick',number_panels)      % set Xticks
set(gca,'YTick',number_batteries )  % set Yticks
set(gca,'ZTick',current_zticks )  % set Yticks
grid on

enter image description here

My code for the colorbar commands is based on: http://www.mathworks.es/es/help/matlab/ref/colorbar.html

Hope this helps, I will try to add the title to the colorbar...
