做插值:(需要到入Rbf函数:from scipy.interpolate import Rbf)func = Rbf(lon,lat,data,function=‘linear‘)rain_data_new = func(olon,olat) 或griddata插值rain_data_new = griddata((lon,lat), data, (olon,olat), method='linear') 注:由于Rbf插值要求矩阵可逆,所以在经纬度列表时,不能有相同的两行。
scipy.interpolate.interp1d可以创建一个线性插值函数: >>> >>> from scipy.interpolate import interp1d >>> linear_interp = interp1d(measured_time, measures) 然后可以在感兴趣的点估算结果: >>> >>> interpolation_time = np.linspace(0, 1, 50) >>> linear_results = linear_interp(interpolation_...
从 SciPy 1.7.0 开始,由于技术原因,该类不允许传递自定义可调用对象,但这可能会在未来的版本中添加。thin_plate_spline smoothing可以通过增加参数给出不精确的插值 参考文献 How can I perform two-dimensional interpolation using scipy?devpress.csdn.net/python/62fd2eaec677032930802ec8.html https://stack...

SciPy的interpolate模块提供了许多对数据进行插值运算的函数,范围涵盖简单的一维插值到复杂多维插值求解。当样本数据变化归因于一个独立的变量时,就使用一维插值;反之样本数据归因于多个独立变量时,使用多维插值。 class scipy.interpolate.interp1d(x, y, kind=’linear’, axis=-1, copy=True, bounds_error=None, ...
