示例

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_interp2d *interp = kml_float_interp2d_alloc(kml_float_interp2d_bicubic, xSize, ySize);
kml_float_interp2d_init(interp, xArr, yArr, zArr, xSize, ySize);
size_t idx = kml_float_interp2d_idx(interp, x, y);
