c = multibandread('paris.lan', [512, 512, 7], 'uint8=>uint8',...
128, 'bil', 'ieee-le', {'Band','Direct',[4 3 2]});
imshow(c)

Have 3 edit fields, one for each ban. The user can type into it. If you're using GUIDE, you can do
band1 = str2double(handles.edtBand1.String);
band2 = str2double(handles.edtBand2.String);
band3 = str2double(handles.edtBand3.String);
bandsToUse = [band1, band2, band3];
multiBandImage = multibandread('paris.lan', [512, 512, 7], 'uint8=>uint8',...
128, 'bil', 'ieee-le', {'Band','Direct',bandsToUse });
imshow(multiBandImage)

Thank you. but i want pixels range to be user defined. the code given below:
im=multibandread('paris.lan',[512,512,7],'uint8=>uint8',... 128,'bil','ieee-le',{'Band','Direct',[x,y,z]}); 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));
b(k)=double(t_value(39,334));
x1(k)=double(t_value(486,115));
y1(k)=double(t_value(486,116));
z1(k)=double(t_value(487,115));
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];
axes(handles.axes1);
plot(d,avg,'r',d,avg1,'g');

See this link to format your code properly.
You can do the same thing with edit fields for user input. Or you can display one frame and ask the user to draw a box over it with imrect() or rbbox().
