How does YALMIP pre-allocate memory to constraints?

[mingluo-feng]

Hello, I have defined a very large number of constraints using YALMIP and the process has taken a long time without pre-allocating memory. Is there any way to pre-allocate memory when constructing constraints for optimisation models using YALMIP? Thank you!

There is no such thing. If you have poor performance, you've either vectorized poorly, or you are creating complicated expressions. Impossible to know without reproducible code

OH, thank you very much. Now there's a direction of improvement for me.
