NUMERICAL METHODS ITERATION PROCESS

Hello! I am writing a code on MATLAB for an iteration but keep getting the error below. I cannot seem to figure out where the error comes from. Any help will be appreciated.

hello

you should also post the code itself not just a screen shot

The error is from the timeJ variable. It seems that the number of elements in array timeJ are less than 1000, which you are querying for in the line

plot(timeJ(1:k+1), normrJ)

If you attach the code as an m file along with all the variables, it would be easy to debug the issue
