How can Capula used to obtain a correlation coefficient between the two vector?

Hi everyone.

I have a data matrix that uncludes input features for predicting electricity price and I want to obtain a correlation coefficient between each column of this data matrix and the price vector using Copula in Matlab.There are several Copula function in Matlab , but I dont know which one and how to use?Please help me. thanks alot.

Why don't you simply use the 'corr' function to compute the correlation coefficients?

My teacher asked to use the Copula functions in matlab,Jeff Miller.

[Jeff Miller]

If you have data and want to estimate correlations via copulas, then your teacher probably wants you to use the copulafit function

Just copulafit?What function should I use for data between zero and one?

Please, write me its code.Thanks.
