我正在從文本文件中讀取磁場數(shù)據(jù)。我的目標(biāo)是正確有效地加載網(wǎng)格點(diǎn)（3 維）和相關(guān)字段（為簡單起見，我將在下面假設(shè)我有一個(gè)標(biāo)量場）。我設(shè)法讓它工作，但是我覺得有些步驟可能沒有必要。特別是，閱讀numpy文檔可能是“廣播”將能夠發(fā)揮其魔力對我有利。import numpy as npfrom scipy import interpolate# Loaded from a text file, here the sampling over each dimension is identical but it is not requiredx = np.array([-1.0, -0.5, 0.0, 0.5, 1.0])y = np.array([-1.0, -0.5, 0.0, 0.5, 1.0])z = np.array([-1.0, -0.5, 0.0, 0.5, 1.0])# Create a mesh explicitelymx, my, mz = np.meshgrid(x, y, z, indexing='ij')  # I have to switch from 'xy' to 'ij'# These 3 lines seem oddmx = mx.reshape(np.prod(mx.shape))my = my.reshape(np.prod(my.shape))mz = mz.reshape(np.prod(mz.shape))# Loaded from a text filefield = np.random.rand(len(mx))# Put it all togetherdata = np.array([mx, my, mz, field]).T# Interpolateinterpolation_points = np.array([[0, 0, 0]])interpolate.griddata(data[:, 0:3], data[:, 3], interpolation_points, method='linear')真的有必要像這樣構(gòu)造網(wǎng)格嗎？有沒有可能讓它更有效率？
