How to put a variable equal to a vector in an if cycle

Hi all,

i'm trying to to find a way to have this example:

for t=2:365
TIMEFAILURECOG= [2 4 10 50];
Matrixdiff=[0,TIMEFAILURECOG];
DIFFERENCE=diff(Matrixdiff);
INDEXCOG1=find(DIFFERENCE>2);       
INDEXCOG2=find(DIFFERENCE<=2);   
DD=TIMEFAILURECOG(1,INDEXCOG1); 
BB=TIMEFAILURECOG(1,INDEXCOG2); 



    if t==TIMEFAILURE(1,INDEXCOG1) % for every t equal to each value of TIMEFAILURECOG(1,INDEXCOG1)
        y=6;
    elseif t==TIMEFAILURECOG(1,INDEXCOG2) % for every t equal to each value of TIMEFAILURECOG(1,INDEXCOG2) 
        y=4;
    else
        y=0;
    end

end

Thanks to anyone who can help me!

My guess

% your data
TIMEFAILURECOG= [2 4 10 50];
Matrixdiff=[0,TIMEFAILURECOG];
DIFFERENCE=diff(Matrixdiff);
INDEXCOG1=find(DIFFERENCE>2);       
INDEXCOG2=find(DIFFERENCE<=2);   
DD=TIMEFAILURECOG(1,INDEXCOG1); 
BB=TIMEFAILURECOG(1,INDEXCOG2);

% set t as a vector
t = 2:365;

% preallocate y as long as t
y = zeros(size(t));

% set y values according to t
y(ismember(t,DD)) = 6;
y(ismember(t,BB)) = 4;
