Why do I get the error "illegal use of reserved keybord "while""?

6 visualizzazioni (ultimi 30 giorni)
I need to run the following code, where the function @opt is already defined. When I try to run it, I get the error "illegal use of reserved keybord "while"". Actually, the "end" that is not well located is not recognized by matlab as an end (it appears written in black instead of blue). Why does this happen and how can I fix it? Thanks a lot in advance.
if true
% E3=zeros(50,50,4);
rn=sqrt(2*(1-cos(2*pi/n)));
for k=1:50
k
for j=1:51-k
alfa=k/52;
beta=j/52;
gamma=1-alfa-beta;
alfagorro=alfa/(1-beta);
gammagorro=gamma/(1-beta);
H=1;
Hgorro=H;
F=(n-1-H)/2;
[f,c]=fmincon(@opt,[1 1 1],[],[],[],[],[0 0 0],[],[],options);
costoviaH=pe/(2*f(2))+pv*[2*T0+t*(a*alfa*Y/(H*n*f(2))+b*alfagorro*Y/(H*n*f(2))+a*gamma*Y/(2*n*(n-1)*f(2))+b*gammagorro*Y/(2*n*(n-1)*f(2)))];
costoviaF=pe/(2*f(2))+pv*[F*rn*T0+(2*(F-1)+1/2)*t*(a*gamma*F*Y/(n*(n-1)*f(3))+b*gammagorro*F*Y/(n*(n-1)*f(3)));
while costoviaH<costoviaF && H<n-1
H=H+2;
Hgorro=H;
[f,c]=fmincon(@opt,[1 1 1],[],[],[],[],[0 0 0],[],[],options);
costoviaH=pe/(2*f(2))+pv*[2*T0+t*(a*alfa*Y/(H*n*f(2))+b*alfagorro*Y/(H*n*f(2))+a*gamma*Y/(2*n*(n-1)*f(2))+b*gammagorro*Y/(2*n*(n-1)*f(2)))];

You forgot to paste the error message. "keybord" is not even an English word, and it's not in your code either so I know that's not the real error message. Please paste in ALL the red text, including line numbers, lines of code, everything . Don't snip or paraphrase like you did.

Both times you use "costoviaF" (lines 24 and 17) you fail to close the bracket at the end of your line.

Wow, it was a very simple mistake, thank you very much, now it is working!
