Hello Huitian Mao,
I hope this will be helpful. I've attached a sample excel sheet of gender and income too. Change the location of excel sheets and run the code. It works as per your requirement.
%Assumptions: 
%Both excel sheets have same number of rows
%1st coloum is social serial number and 2nd coloum is gender or income in
%both the sheets
clc;
[num,txt,raw] = xlsread('C:\Rahul\gender.xls');
[num1,txt1,raw1] = xlsread('C:\Rahul\income.xls');
num1=num1(:,2); %income
MaleIncome=0;
NumberOfMales=0;
MaleAvgIncome=0;
FemaleIncome=0;
NumberOfFemales=0;
FemaleAvgIncome=0;
for i=1:10
  if char(txt(i))=='M'
   MaleIncome=MaleIncome+num1(i);
   NumberOfMales=NumberOfMales+1;
  elseif char(txt(i))=='F'
   FemaleIncome=FemaleIncome+num1(i);
   NumberOfFemales=NumberOfFemales+1;
  end
end
MaleAvgIncome=MaleIncome/NumberOfMales;
disp('Male average income : ')
disp(MaleAvgIncome);
FemaleAvgIncome=FemaleIncome/NumberOfFemales;
disp('Female average income : ')
disp(FemaleAvgIncome);
