## Main Question or Discussion Point

**Different correlation coefficient results between Matlab and Excel. Please Help!!**

I have two sets of dat as below. A problem is that matlab and excel returns a different value of correlation coefficient (i.e., 0.801 from Excel and 0.786 from Matlab).

For Matlab, I used the function: corrcoef(DataA, DataB). For excel, I used the function "Correl".

Would you please advise me which one is correct? I found that the excel uses different function from the one used in Matlab. I do not know how to write a function here, so I linked them as below.
