Dear Sir/Miss
I'd like to know if there is a method for Igor to calculate the correlation coefficient and fitting slop of each column in two matrix? I would so pretty much appreciate it if you can give me a response!
Best,
Fuzhen
It would help if you provided more details in your question. You may want to approach this using a stats operation. For details execute:
DisplayHelpTopic "StatsLinearRegression"
You can get a typical correlation coefficient for two arrays using StatsCorrelation. For more information execute:

You can also use the standard curve fitting to fit a line to your data (Analysis Menu->Quick Fit->Line) and then check the V_Rab and V_r2.
