I have a table that looks like this
A B C Var1 Var2 Var3
--- --- ----------- ---- ---- ---
1000 10 'Index' 1 2 3
3000 20 'Index' 2 3 4
5000 30 'NotIndex' 3 4 5
5000 40 'Index' 4 5 6
I want to manipulate Var1, Var2...…based on the the values in A, B and C…I have an exteranl function that does the manipulation needed.
If I use rowfun I can only manipulate one VaR at a time. If I use varfun then I cant figure out how to pass A, B and C

When C = 'Index', then A*B*Var1, A*B*Var2 etc...
else A+B+Var1, A+B+Var2...
so result should be
Var1 Var2

Do you see why you didn’t receive a proper answer? More illustrations needed, it’s not clear atleast for me.

Hi Niraj,
You can get multiple output using rowfun as well.
Please refer to the following link:https://www.mathworks.com/help/matlab/ref/rowfun.html#bty705b-4
As shown in this link you need a function that returns 3 outputs (Var1,Var2,Var3 in your case).
