MATLAB: Please help me sort this out

please can someone help me with a very simple coding… i know its simple but i'm not getting…

i 2 matrix with dimensions below,

 A = with 13 rows and 125 columns
 B = with 1 row and 125 column,

i want to find which row of A matches with B if it does not match, i want to get the row which matches with most columns of B

please someone help me to sort it out, eg if A is,

 34    44    55     66
 23    33    22     27
 21    44    66     34
 if B = 23 33 22 27 i want ans = 2
 if B = 27 44 66 34 i want ans = 3

A=[4    44    55     66
23    33    22     27
21    44    66     34]
B=[23 33 22 27]
[~,ii]=max(sum(ismember(A,B),2))

MATLAB: How to make each pair of pixels from the matrix in a row major order

Hello Subroto. I have used a couple of steps to convert A into a vector of paired up pixels and stored it in A_paired.

>> A=[43   36   31   35   35   29   29   25

I hope this was helpful. :)

MATLAB: I cannot create that array in Matlab !

It will tell you, with a red squiggly underline where the problem is. In your case you have this "number" in there:

30.00.39.64

You cannot have a number with three decimal points in it.
