data fitting that output eigenvalues and eigenvectors of the data

I have the follwing data points constituting three curves.

Is there any MATLAB function that perform regression over these points and output the eigenvectors and eigenvalues and their weights for each curve?

You can do regression, check the function
Note that eigenvalues and eigenvectors are for a matrix. Read about eig for this.

Thanks for your answer! I guess I did not phrase my question correctly.
I want to fit the curves in an equation of the form so that if I plot it I get the same curves in the figure. The eignevalues are the lamdas, the eigenvectors are An, and a_n is constant.
