how can i compare Pexit which is the output of outlet to Pback given. By approximating after checking for greater/less than conditions.Ive already wrote code but main function is that of nozzelcalculator that result Pexit

for n=1:1:10 %%dont want it to have necessarly specific endingnumber

outlet=Pexit;

if

for n=1:1:10      %%dont want it to have necessarly specific endingnumber
    % outlet is an output of function which takes inputs, one being As which is location we guess at first
    % im given Aexit
    % iF Pexit>Pback have to new location of As by taking midpoint of first guess and Aexit
    % if Pexit<Pback have to take As by taking midpoint of third and second guess
    % do this till we can approximate  Pexit to Pback
    
    outlet=Pexit;
    if Pexit > Pback  
        As=An+Aexit/2;
    elseif Pexit < Pback
        As=As+As-1/2;
    end
end
%im strugling to create this part comparing
