kml_?_spline2d_set

Set zarr to z at grid point (i, j).

Interface Definition

int kml_float_spline2d_set(const kml_float_spline2d *spline, float zarr[], const size_t i, const size_t j, const float z)

int kml_double_spline2d_set(const kml_double_spline2d *spline, double zarr[], const size_t i, const size_t j,

const double z);

Parameters

Parameter	Type	Description	Input/Output
spline	kml_float_spline2d, kml_double_spline2d	Pointer to an interpolation object.	Input
zarr	float, double	Array that stores the value of z.	Output
i	size_t	Index in the x direction.	Input
j	size_t	Index in the y direction.	Input
z	float	Value of z to be changed.	Input

Examples

const size_t xSize = 4;
const size_t ySize = 4;
float xArr[4] = {1,1.33,1.67,2};
float yArr[4] = {1,1.33,1.67,2};
float* zArr = (float*)malloc(xSize * ySize * sizeof(float));
float x = 1;
float y = 1;
float z = 0;
kml_float_spline2d *spline = kml_float_spline2d_alloc(kml_float_interp2d_bicubic, xSize, ySize);
kml_float_spline2d_init(spline, xArr, yArr, zArr, xSize, ySize);
kml_float_spline2d_eval(spline, xArr, yArr, zArr, x, y, xacc, yacc, &z);
