Stata program: Re-fit pre-existing code: svd command (singular value composition) to avoid conformity issue (Lee-Carter model with output b and k required) -- 2

Hi everyone, I am working on a little project and I need to refit the code I have so it does the exact same thing as before but does not have a conformity issue with the svd command. Basically, the code works with a dataset (age groups in 5 year intervals) where in the matrix m>n, but I need to re-fit it to the same dataset with age groups intervals of year by yeay - which creates svd conformity issues. I have looked up some things but couldn't find a way to do it so far. Attached is: The code with the original 5x1 data The new data of 1x1 where I am trying to get the code working. Have a look at the code and run it through the old data and then the new, you'll see the error coming up. I basically need everything to do the same and that the code returns b and k because I need these for further calculations. Thanks :)
