Hi folks,
I have 2 tables. A is 256x54 and B is 1x54.
I want to correlate each of the 256 values in each column of table A to the corresponding value in table B, and then find the index within table A that gives the best correlation.
Is this possible? So far I have been unseccessul in applying the \ operator as per the documentation in here:
Attached are my tables!

You want to find the index of the closest number, purely based on the value?
So for the example data below it should return 1 and 3?
A = 3×2 table
Var1 Var2 ____ ____ 1 10 2 20 3 30
B = 1×2 table
Var1 Var2 ____ ____ 1.4 26
