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"
