Hi,everyone,

I tried to find out the mathematic relationship expression 
of two datasets listed as follows:

A                      B

0.994908571          30.96%

if A is the independent vairable and B is the dependent 
variable, how to find out their mathematic relationships in 
Matlab? I have tried in EXCEL but it is not simple linear, 
exponential, log~~

Thank you very much.
