kml_?_interp2d_set

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

Interface Definition

int kml_float_interp2d_set(const kml_float_interp2d *interp, float zarr[], const size_t i, const size_t j, const float z)

int kml_double_interp2d_set(const kml_double_interp2d *interp, double zarr[], const size_t i, const size_t j,

const double z);

Parameters

Parameter	Type	Description	Input/Output
interp	kml_float_interp2d, kml_double_interp2d	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

float* zArr = (float*)malloc(xSize * ySize * sizeof(float));
size_t i = 1;
size_t j = 1;
