how to execute (cell) in operation (if then)? , data types: string, taken from the data excel

Asked by Roza on 4 Jan 2013

I want to compare two string data. but when I use the expression for and if, it can not be run.

i'm sorry... this is my code... I am a beginner, please your help.

clear;
clc;
[data2,follower]=xlsread('follower.xlsx');
[data3,mention]=xlsread('mentions.xlsx');
[data5,wg]=xlsread('wg.xlsx');
n_vertex=length(follower(:,1));
wg=0;;
for i=1:n_vertex
  for j=1:n_vertex
     if isequal(follower{i,1}==mention{i,1}, follower{i,2}==mention{i,2})
         if follower{i,1}==wg{i,1}
          wg=wg+data5(i,1)+1;
         end;
      end;
  end
end

============================================================================== Error using ==> eq Matrix dimensions must agree.

Error in ==> oo at 17 if isequal(follower{i,1}==mention{i,1}, follower{i,2}==mention{i,2})

================================================================================ I want to make it again from (1) to n_vertex. but it seems there is something wrong .. please help, thank you.

Post your code

It is impossible to guess what you have written as code and what "it cannot run" exactly means. Please post the code, example data and explain, what's going wrong. E.g. a copy of the error message would be helpful, if there is one.
