u=multibandread('paris.lan',[512,512,7],'uint8=>uint8',128,'bil','ieee-le'); Nof_bands=7; for k=1:Nof_bands t_value=u(:,:,k);
x(k)=double(t_value(38,333));
y(k)=double(t_value(38,334));
z(k)=double(t_value(39,333));

b1(k)=double(t_value(487,116));
avg(k)=double(x(k)+y(k)+z(k)+b(k))/4;
avg1(k)=double(x1(k)+y1(k)+z1(k)+b1(k))/4;
end
d=[1:1:7];
figure(1)
plot(d,avg,'r',d,avg1,'g');

Do you want the user to give input by clicking at a particular point, or using an input field?

User input from mouse Please check the above link. If you want 4 points as you mention in your comment, you can do
[x,y] = ginput(4)
The link in the answer gives more documentation on what you need to do for different use cases.

It isn't clear from your comment what the error is or where it is occurring. I would advise using an array instead of making several variables with names like x,xx,xxx,xxxx and so on. You also should improve your indentation. Each subsequent line inside a loop doesn't need to be progressively indented with respect to the previous line. The indent should be the same for all lines inside a condition, function, or a loop.
