Description Retrieves the coefficient of the polynomial term that corresponds to the given i, j, and k polynomial indices of a specified polynomial surface
Syntax coef = GetPolynomialSurfCoefIJK ( n, i, j, k )
Parameters coef (Double) The IJKth coefficient
n As Long Node number for the polynomial surface.
i As Long The index i used in the x component of the polynomial term.
j As Long The index j used in the x and y components of the polynomial term.
k As Long The index k used in the y and z components of the polynomial term. If i=j=0 then k simply represents the term number.
Remarks This function retrieves the coefficient of the polynomial term that corresponds to the given i, j, and k polynomial indices of a specified polynomial surface. Note that the indexes that define the power of each term of the surface are defined according to:
i.e. if we wanted to get the coefficient for the y^3 term (i.e term 16) then:
And so we could call this function with either (i,j,k) = (3,3,0) [using the index values as calculated above], or (i,j,k) = (0,0,16) [using k as the term number when i=j=0]
