separating strings one by one

   N=length(str);
   count=1;
   for k=1:N
       x=str2double(str(k));
       if isnan(x)==0
           str(count)=x(k);
           count=count+1;
       disp(x);
       end
   end

This is currently the code I have right now but it keeps giving me an error because the "index exceeds matrix dimensions on the line: str(count)=x(k); What am I doing wrong?

your ‘x’ variable is a scalar, by definition a (1x1) ‘array’. So ‘x(k)’ is only valid for x=1.

This will likely eliminate that error:

str(count)=x;

is there any way that I can call for the 4th and 8th number of this code??? like if my result after it is:1256893490 then how can I pull out the 4th and 8th number of it? Thank you!

My pleasure!

I don’t know what ‘str’ is.

I assume that you would address them as:

str(4)
str(8)

respectively.

You can assign them as separate variables, but it is best to simply refer to them as elements of the vector.
