i have a for loop which generates the BERR, and Received power, i want to find the number of times the if else statement is true,so to draw a bar graph, could anyone help me out?

if BERR<10^-5
    display ('pass stage 1')
        if PRx>-78
      display ('pass stage 2') 

      else
          display ('fail') 

      end
  else
        display ('fail') 

end

passed1 = 0;  
passed2 = 0;
fail1 = 0;
fail2 = 0;

if BERR<10^-5
    display ('pass stage 1')
        if PRx>-78
      display ('pass stage 2') 
        passed2 = passed2 + 1;
      else
          display ('fail') 
        fail2 = fail2 + 1;
      end
  else
        display ('fail') 
    fail1 = fail1 + 1;
end

Myself, I'd probably be thinking in terms of

passed = sum( (BERR<10^(-5)) & (PRx > -78) );

thnk you Mr.Walter Roberson for the reply, it has been most helpful. ive got another question, say i have 3 different received powers,PRx1,PRx2,PRx3 generated,and for each PRX value i have a BERR generated in the loop,my question is, how do i compare each of these BERR values to their respective PRx value to do the same task as above

this is the code that i have

edtberr=reshape(berra.',3,[]); %so that each row  will be BERR values for one of the PRX value

if edtberr(1,:)<10^-5
    display ('pass stage 1')
     if PRx(!)>-78
       display ('pass stage 2') 
       success= success+1;  
     else
         display ('fail') 
         fail=fail+1;   

       end
  else
        display ('fail') 
  end

An evaluated expression is true when the result is nonempty and contains all nonzero elements (logical or real numeric). Otherwise, the expression is false.

With that emphasized, please reconsider "if edtberr(1,:)<10^-5"
