for loop with fminsearch

%I couldnt make array values of Theta_2

u=deg2rad(13)

eqn1= @(t1, u) u+atan(sin(t1)./(1-cos(t1)))-pi/2 % theta1 t1 olarak tanımlanmıştır.

Theta_1_initial= (fminsearch(@(t1)norm(eqn1(t1, u)),u))

Theta_1=linspace(Theta_1_initial,pi/2,100)

for i=1;100

Theta_2(i)=THETA (Theta_1(i),u)

end

function [Theta_2] = THETA (Theta_1,u)

eqn=@(Theta_2,Theta_1,u) cos(Theta_2)+sin(Theta_2).*tan(pi/2-atan(sin(Theta_2)./(cos(Theta_1)+sin(Theta_1).*tan(u)-cos(Theta_2))))-cos(Theta_1)-sin(Theta_1).*tan(u);

Theta_2=fminsearch(@(Theta_2)norm(eqn(Theta_2,Theta_1,u)),Theta_1);

There is a typographical error:

for i=1;100

↑← HERE

Change that to a colon and it works —

%I couldnt make array values of Theta_2
u=deg2rad(13)

u = 0.2269

eqn1= @(t1, u) u+atan(sin(t1)./(1-cos(t1)))-pi/2 % theta1 t1 olarak tanımlanmıştır.

eqn1 = function_handle with value:
    @(t1,u)u+atan(sin(t1)./(1-cos(t1)))-pi/2

Theta_1_initial= (fminsearch(@(t1)norm(eqn1(t1, u)),u));
Theta_1=linspace(Theta_1_initial,pi/2,100);
for i=1:100
    Theta_2(i)=THETA (Theta_1(i),u);
end

Theta_2

Theta_2 = 1×100

0.4311 0.4651 0.4764 0.4876 0.4740 0.5102 0.5215 0.5328 0.5440 0.5553 0.5666 0.6068 0.5892 0.6005 0.6117 0.6230 0.6343 0.6456 0.6569 0.6682 0.6455 0.6907 0.7020 0.7133 0.7246 0.6991 0.7471 0.7963 0.7697 0.7419

function [Theta_2] = THETA (Theta_1,u)
eqn=@(Theta_2,Theta_1,u) cos(Theta_2)+sin(Theta_2).*tan(pi/2-atan(sin(Theta_2)./(cos(Theta_1)+sin(Theta_1).*tan(u)-cos(Theta_2))))-cos(Theta_1)-sin(Theta_1).*tan(u);
Theta_2=fminsearch(@(Theta_2)norm(eqn(Theta_2,Theta_1,u)),Theta_1);
end

Thanks so much

As always, my pleasure!
