Index exceeds matrix dimensions Economic Model

Hello everybody, I have a question. Perhaps any of you could be kind enough to help me. It has to do with the firing part of my model:

• f=randperm(length(workforce));
• f=f(1:-vacancies(i));

Now normally what happens you get something like this: (when there are 2 vacancies for i(the firm)):

• f=[3,2,3,4,12];
• f=f(1:--2)

And it returns: [3,2], so that these are both fired. However I am adjusting the model and now I have a situation where it’s possible that: (still when there are 2 vacancies)

• f=[3];
• f=f(1:--2)

And it doesn’t work, because there aren’t 2 to fire. Therefore I get an error: Index exceeds matrix dimensions. Instead I would like the model to fire the one and leave the other vacancy unfulfilled. I have been wrapping my head around this and would appreciate any suggestions!

Thanks in advance!

Hello Erdtsieck,

Probably the easiest solution is to simply ensure the final index doesn't go beyond the max length of the array:

f=f(1:min(-vacancies(i),numel(f)));

Thank you perfect!
