I am trying to simply do the following cVec = {a,b,c,d} From another expression, I obtain another vector, say, ...

So here's the problem a=1;a=2 works because of the HoldFirst attribute of Set, so that it ...

I want to do the following. Say I have a list: test = List[a,b,c] and I now want to assign some value to elements of that list, so that say if I assign 4 to a, ...

My main question is how to assign values to symbolic arrays, in an efficient way. The code below is a simplified version of what I am trying to do and the output I get. Note that because I am using ...
