I have two sets of precomputed data, namely Voltage,V and Resistance,R. For a value of Voltage, there is a Resistance value. I calculate new Voltage and need to know the (V,R) pair from the precomputed data sets which is closest to this new voltage value and also the corresponding resistance. How may I do that?

Hope the below example helps you. I have created two sample matrices "V" and "R" and the new Voltage is named as "vin". "Vout" gives the voltage closest to "vin" from "V" matrix and "Rout" will be the corresponding Resistance value from "R" matrix.
V=[ 0 50 2 54 1 56 3];
R=[2 10 3 12 5 13 4];
[Vout index]= min(abs(vin-V));
