Given a set of measurements of dependent variables in a vector, Y, that vary with one independent variable in a vector, X, calculate the interpolating polynomial. Output is the interpolated value for a given value of x, as well as the condition number of the Vandermonde coefficient matrix.

Mr. Google was not clear enough...
What is the "condition number of the Vandermonde coefficient matrix"??
:-/
(the rest was easy.. ;-) )
J.R.!

FYI: The condition number of the Vandermonde coefficient matrix is just the norm of the matrix times the norm of its inverse. Cheers.
PS: Wikipedia will just lead you to a paid wall. Don't waste time.
