Reply To: What is the DIV meaning in *VOPER command when both par1 and par2 are arrays?

Hey,

I apologise for the confusion what i meant was DIV in *oper command is indeed for division.

The problem might be with your syntax that is why i provided those links.
if you check the 2nd link 

Here this is the correct syntax for getting 1st derivative of an array D wrt time t in array A and save it in E. You just have to replace DER1 to DIV and point to your arrays.

Let me know how it goes.
