UDF function on Matrix

[Guest]

Dear all,
I want to write my own function which will calculate Eigen values of any
given matrix.
So the first line of my program is looking like:

Function eigen (data as " ") as " "

My question is what I should give in between two quotation marks above? What
is the way to read a Matrix for this program?

Thanks and regards,

Function eigen (data as Range)

where data would refer to the cells of the matrix .
