how to plot a hyperspectral image in matlab?

Hi,

I've used these 2 lines

SIZE = [1208,307 ,191];
X = multibandread('dc.tif', SIZE, 'int16',1, 'bsq', 'ieee-le');

to read a hyperspectral image, now i how to plot/display the image on a graph? I also want to add noise to it

Thank you

that is easy. use this expression:imshow(X(:,:,n),[]), n is band, from 1to 191.

sir,

I want to select different bands and imshow them, I use subplot to display these pictures in an image, but there was something wrong with my code.

subplot(2,1),imshow(x(:,:,2),[]);

??? Error using ==> subplot at 188

Unknown command option.

when I use" subplot(2,2,1),imshow(x(:,:,2),[]);"this, it works. why?

Thank you

subplot() can take either one number such as 121, or it can take 3 numbers such as 1, 2, 1, but it cannot take two numbers. The form with a single number is not recommended. You should be using subplot in the form

subplot(M, N, k)

to choose plotting area #k out of an M x N array of plots, with the areas numbered across. So for example, subplot(2, 3, 4) would be plot #4 out of a 2 x 3 array of plots that were numbered

   1 2 3
   4 5 6
