HI,
WHAT I HAVE DONE IS.
1.RED ONE IMAGE STOREDF AS IMAZE NAME=A;
2.RESIZE IT INTO 128*128 MANNER
3.I WANT THESE PIXEL ELEMTS IN SINGLE COLUMN
SO I CODED AS B=RESHAPE(A,C,D) WHERE C =128*128 AND D= 1
ERROR IS
z=reshape(a,c,d);
??? Error using ==> reshape
To RESHAPE the number of elements must not change.
PLEASE CORRECT ME?
BELOW IS CODE WHAT I HAVE DONE. a=imread('C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures\Water lilies.jpg');
b=imresize(a,[128 128])
b=imresize(a,[128 128]);
c=128*128;
d=1;
z=reshape(a,c,d);

b has 128*128=16384 elements. You cannot reshape it so that it has 3 columns because 16384/3 is fractional. What is your end goal?
