MATLAB: A simple Question about loops

for looploops

Hi All
for exemple:
%%
    % 
 a=[1 2 3 5 4 8];
 v=[]
v(1)=a(1);
for k=2:length(a)
    if(k<3)
        v(k)=v(k)*(k-1);   
    else
    v(k)=(v(k-1)+(v(k))/3);
    end    
end
i get this error: Attempted to access v(2); index out of bounds because numel(v)=1.
why? thanks for yor help

Best Answer

You initialize v incorrectly. Try it this way....
a=[1 2 3 5 4 8];
 v=ones(length(a));
v(1)=a(1);
for k=2:length(a)    
    if(k<3)
        v(k)=v(k)*(k-1);      
    else
        v(k)=(v(k-1)+(v(k))/3);
    end    
end
