hello im doing an iteration and everytime i execute my code it brings out and error
clc
clear
format longg
gama=0.75;
ppc=667;
tpc=408;
pts=2500;
tts=35+460;
tws=245+460;
l=10000;
theta=0;
x=10;
pws=(pts)+(0.25*(pts/100))*((l*cos(theta))/(100))
for i=1:x
pavg(i)=(pws+pts)/2
tavg=(tws+tts)/2
tpr=tavg/tpc
ppr(i)=pavg(i)/ppc
z(i)=input('enter z: ');
s(i)=(0.0375*gama*l*cos(theta))/(z(i)*tavg)
pws=pts*exp(s(i)/2)
if s(i)==s(i-1);
display('done')
break
else
display('u need more iterations')
end
end
the error comes out because matlab executes the if statement before another value for "s" has been calculated i want it to wait till a second value of "s" is calculated to execute the if loop i know this code is kinda amateur but bare with me please im new to matlab coding, and if u have any suggestion on a simplest form of this iteration please do help.

Matlab execute the lines of your code one after another. The if statement will be executed after the calculation of s(i). What is the error message? have you tried to debug your code?

You need to initialize s, and the for loop should start at i=2, because if i is equal to 1, you can't write s(i)==s(i-1), i-1=0 is not allowed by Matlab
