address.xlsx

Hi , i need your help please ,

i have vector contains hex numbers such as :(16-bits)

(0000 0011 1100 0000)

i need select the middel bits from ( b7-b10) then read its as decimal asuch as = 15

i alraedy did that as in the code , but the problem is just work with last row in the vector for my data base ('address.xlsx')! this data base contains 16 rows!

i need find and stor the resuts as vecotr for all my data base numbers not just last elment!

clc;
clear all;
[~,~,dat]= xlsread('address.xlsx');
num=dat(:,1);
 for n=1:numel(num)
b=hex2dec ([dat(:,1)]);
b1 = hex2dec('000fff0');
%    b = hex2dec ('6e206b'); % for example its work with one elemnt
format hex;
 x=bitand(b1,b);
 cc=dec2hex(x);
   bin=hexToBinaryVector(cc);
      ccz=bin((end-flip(7:10)+1));% how can expand this term  for all vector!
   bp=num2str(ccz);
  bp11= bp(find(~isspace(bp)));
 v1= bin2dec(bp11);
 end
