Description |
xval |
double |
An input variable for the AKISPL function. - Generally, this variable is time or a function that returns a real number. |
zval |
double |
An input variable for the AKISPL function. - The second variable is necessary for three dimensional spline functions. - This variable must be a function that returns a real number. Otherwise, 0 is applied. |
identity |
int |
The identity of Spline. |
order |
int |
The interpolation method for the functions (return the value if 0, return calculation for 1st order differential equation if 1, and return calculation for 2nd order differential equation if 2) 1) order = 0 2) order = 1 3) order = 2 |
array |
double | |
errflg |
int |
If an error is encountered in invoking Predefined subroutine, this variable becomes true. This variable must be declared as a logical variable |
