% Script file for Problem 2 on exam 2.
% You shouldn't need to change the next three lines:
load Problem02Data;  %This load the 256 x 256 x 3 matrix X.
X=double(X);          %Change the format for the clustering to work.


% Reshape to get a regular matrix of data (65536 x 3) (fill in one line below)
???

% Perform k-means (fill in one line below).
%  Output should be idx for the index of each data point (which cluster it belongs to)
%  and C for the matrix of centers.
???


% VIsualization section- You shouldn't need to change this.

Im=uint8(zeros(65536,3)); %This creates the matrix in memory with the new colors

for j=1:65536
Im(j,:)=uint8(round(C(idx(j),:)));
