EXPLAIN performance is sometimes influenced by the time it takes to create temporary tables. For example, a query that uses the common subexpression optimization requires temporary tables to be created and analyzed in order to return the EXPLAIN output. The query plan depends on the schema and sta...

I have seen some similar functions in problems where numbers are large and we need to mod a number like 998244353 or 1000000007 (I also noticed they are all prime). I think this function might be modular inverse??? But I don't know why any of this works and how do I use it. I d...
“Explanation holds only when the explanans is conceptually related to the explanandum, and this can occur only at the same level of function.” “As it happens, clouds are natural candidates for the explanans in a scientific account.” “The discussion thus divides between thermodynamics bein...
reductionFcn— Reduction function function handle Reduction function, specified as a function handle. The reduction function reduces the output activations of the reduction layer to a single value and must reduce a dlarray object to a dlarray scalar. This scalar fulfills the role of classIdx in cl...
