Hi all,
I would like to know how to find an optimium value to reach or fit with the final result even if I change other variables as shown:
clear all;
clc;
x=10; y=20;
k=x+y;
f=20; m=10;
t=1; % I need to find the optimum value of t which should be in this case 41
final=k+f+m+t
if final<100
disp('ok')
else
disp('no')
end

In the case you show, if t is 41 then final would be 101, which seems to exceed your desired value of 100.

Don't use clear all. It clears all functions that were loaded to memory, which causes everything to be slower. If you want to clear the variables in a debugging context you can use clear or clearvars. Outside of debugging you should use functions to keep your workspace clean.

Can it be like this, if you want to find value if final>100
clc;clear;
syms x y t k f m
x=10; y=20;
k=x+y;
f=20; m=10;
final=k+f+m+t>=100
t=solve(final,t)
of if you want to find value if final=100
clc;clear;
syms x y t k f m
x=10; y=20;
k=x+y;
f=20; m=10;
final=k+f+m+t==100
t=solve(final,t)
