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);
z = kml_float_spline2d_get(spline, zArr, x, y);
