I have a script already done I just need to add to the code so that i can run the code and store the index of the first 1 that occurs in a vector g. Can anyone help me add to the code to implement it?

for m = 1:200        
x = zeros(200,1); 
x(m) = 1;
x(1) = input('Enter initial positive integer:'); 
k = 1;
while ((x(k) ~= 1) && (k < 200)) 
   if rem(x(k),2) == 0                        
      x(k+1) = x(k)/2; 
   else 
      x(k+1) = 3*x(k)+1;
   end
   k = k+1; 
end
n = k;
x = x(1:n); 
clc 
disp(sprintf('x(1:%1.0f) = \n',n)) 
disp(sprintf('%-8.0f',x)) 
[xmax,imax] = max(x); 
disp(sprintf('\n x(%1.0f) = %1.0f is the max.',imax,xmax))
density = sum(x<=x(1))/x(1);
disp(sprintf(' The density is %5.3f.',density)) 
close all 
figure
plot(x) 
title(sprintf('x(1) = %1.0f, n = %1.0f',x(1),n));
figure
plot(-sort(-x)) 
title('Sequence values sorted.')
I = find(rem(x(1:n-1),2)==1); 
if length(I)>1 
   figure  
   plot((1:n),zeros(1,n),I+1,x(I+1),I+1,x(I+1),'*')
   title('Local Maxima')
end

I understood that you want to find the first occurrence of 1 in a vector.Can you try this:

index=find(vector==1,1,'first')
