Hey everyone.
Without going into too much unnecessary detail, I'll try and explain this strange problem I'm having.
I've been writing some optimization code, in which I have a set of starting values (importantly, containing a value N which specifies vector length), which are repeatedly adjusted and rated for suitability using an objective function. All of this takes place in a loop.
The objective function always (purposely) outputs a vector of N+1 values, which is then used as the standard length for the rest of what I'm doing in the loop.
This all usually works absolutely fine, but recently I have come across a set of values where N doesn't increase to N+1 as it usually should, and hence it causes errors in the rest of the code. This set of values is nothing out of the ordinary, and furthermore, when I break the code down and run it in sections with these values, N increases to N+1 as it should - so the error only happens while running in a loop.
Therefore, there doesn't seem to be any problem with my code - so I'm just wondering if anyone has experienced something similar or knows of any bugs that produce this behaviour in Matlab?
Hope that wasn't too complicated. Thanks in advance if you have any advice!
