C Parameters:
C  XMIN      (R)    Minimum 'x' used in polynomials calculation
C  XMAX      (R)    Maximum 'x' used in polynomials calcualtion
C  CC        (R)    The Chebyshev polynomial coefficients                           		   C(0) ... C(N).
C  N         (R)    Polynomial order in 'x' direction
C  X         (R)    The value of 'x' at which the function is to be evaluated
