How are you trying to view the image?
I suspect you need to use uint8 to first convert your doubles to a value between 0 and 255. See here.

Hi, try the code below
% Rescale your matrix in 0-255 range
rescaledMatrix = rescale(yourDoubleMatrix, 0, 255);
% Typecasted to uint8
rescaledMatrix = uint8(rescaledMatrix);
% Display your image
figure; imshow(rescaledMatrix, []);
This might help!

The "q" is generated from "c1" by your algorithm only. Therefore it is not possible for me to comment on how this can be solved.
The code for the 3D scatter plot is below.
close all; clear all;
load q.mat;
r = q(:,:,1);
g = q(:,:,2);
b = q(:,:,3);
plot3(r(:),g(:),b(:),'.');
grid on; box on;
xlabel('Red Channel');
ylabel('Green Channel');
zlabel('Blue Channel');
title('Scatterplot of the Visible Bands');
