array A double-precision array of length three. The values contained in array
depend on IORD. The table below summarizes what array is to contain:
IORD: Array:
0 The interpolated value of
y
Array(0) = y
Array(1) = 0
Array(2) = 0
1 The first partial
derivatives of y with
respect to x and z. Array(1) =
2 The second partial
derivatives of y with
respect to x and z.
Note that:
∂ 2 y
-----------
∂ z∂ x
Array(2) =
Array(3) = 0
Array(1) =
Array(2) =
Array(3) =
errflg A logical (true or false) variable that CUBSPL returns to the calling
subroutine. If CUBSPL detects an error in its calculations, it sets errflg
to true before it returns errflg to the calling subroutine.
CUBSPL accesses data in a SPLINE statement, using the traditional cubic curve-fitting method to fit a
spline to the data, and returns one of the following:
• A value for the dependent variable (y) for each value it receives for the independent variable or
variables.
• The first partial derivatives of y with respect to the dependent variable(s).
