Dear Visha As Damar said, UQLab evaluates the metamodel in a vectorized way. However, there may be rare cases where the best way to evaluate the metamodel is not obvious. For example, see this post: > [@Vectorized mfile-based model with an if statement](https://uqworld.org/t/vectorized-mfile-based-model-with-an-if-statement/1199): > > Dear UQLab Community I have a mfile-based model with this if statement that needs to be true so I can evaluate a performance function according to different metamodel previously established. It is my understanding that the mfile is vectorized, improving the performance of the code by several orders of magnitude, since it allows the evaluation of N different realizations in a single call. Nevertheless, I notice that the if statement that I am using the mfile is never true, but it should be for… If you explain you computational model in more detail, I can hopefully say more about that.
