Is there a good way to avoid junking up code with lots of preallocation lines?
显示 更早的评论
I have a specific set of code that has a lot of little projection pieces, each of which I'd like to be preallocated for speed. However, in doing so, you get a lot of lines like this:
...
cash.PaidOut=zeros(n,500);
cash.PaidIn=zeros(n,500);
cash.TaxesPaid=zeros(n,500);
...
Is there a way to get the same functionality in a more terse style?

cash = struct('PaidOut', zeros(n,500), 'PaidIn', zero(n,500), 'TaxesPaid', zeros(n,500));

You can assign the same value to multiple fields if you want, which I think would help in this case.

Multiple fields at one time/line if that was not clear before.

Beware, though, the copy-on-write behavior.
