How to interpolate values given a starting and end point?

Date: 2024-06-15 12:53:07

I have a voltmeter that I was using to measure voltage on a battery, unfortunatly it wasnt working properly and Im not able to do the test again. Before and after I ran the test I tested the voltage, so I know the real starting (50.6V) and ending (50.3V). My voltmeter recorded the power draw correctly but the values are off, they hover around 18V, how do I interpolate the bad values with a known starting and end point?
 
Example:
 
I know its 50.6 to 50.3 and my recordings are 18.2 to 17.9
 
I want the readings to be 50.6, 50.5, 50.4, 50.3 instead of 18.2, 18.1, 18.0, 17.9. I cant just add the difference because power draw wasnt exactly linear so Im trying to use the interp1 function but it isnt working for me. Thanks!
 

Expert Answer:

:

 
Use the rescale function —
 
 
Vrec = [18.2, 18.1, 18.0, 17.9];
Vrange = [50.6 50.3];
Vres = rescale(Vrec, Vrange(2), Vrange(1))
Vres = 1x4
   50.6000   50.5000   50.4000   50.3000
