Hi,

I have some tables, It's like this

Current ADC

0 511

1 518

2 533

5 580

10 664

15 753

21 861

I want to extract the algebra function from it(different systems with different current curves), Do you know some automatic ways? do you know a function in matlab or excel?

So for example it will give me a function and when I put the adc value I will get the interpolated current!
