Symbolic array pre-allocation only allocates pointers as I understood it from reading the forum. This is causing a major slowdown in code we are looking at
Filling the area with relatively simple expression e.g. '3+sqrt(5)/sqrt(7)' a serious slowdown is noted around the 9000th index.
Would it be possible to allocate memory by defining the sym array (in the definition) with large expressions '3+sqrt(1)+sqrt(2)+sqrt(3)+sqrt(4)+sqrt(5)+sqrt(6)+sqrt(7)' for all elements 1:50000, so that effectively a memory allocation is forced at the definition step. Is this possible in the definition of sym? I tried repmat, but didn't get it too work.
