What's the best way to calculate a 3D (or n-D) centroid?If your n-dimensional vector is in a list [[a0, a1, ..., an],[b0, b1, ..., bn],[c0, c1, ..., cn]], just convert the list to array, and than calculate the centroid like this: import numpy as np vectors = np.array(Listv) centroid = np.mean(vectors, axis=0)

Find center coordinates of regions in a 3d numpy arrayI have a large numpy 3d array (10000, 3, 3). in which I would like to find the center coordinates of each region (clusters with the same number). Each sub-array can have 1, 2, 3 or 4 regions. A subset of my array is: largearray= array([[[1, 0, 0], [0, 0, 2], [3, 0, 2]], [[0, 0, 4], [0, 0, 4], [0, 0, 4]],

5 Best Ways to Find the Center of a Set of Points Using PythonNumPy, a powerful numerical processing library, provides a highly efficient array structure that can be used to calculate the centroid of a set of points. With NumPy, you can perform the entire calculation in a vectorized manner, which can significantly speed up the process for large datasets.

What’s the best way to calculate a 3D (or n-D) centroid?centroid = average(x), average(y), average(z) where x , y and z are arrays of floating-point numbers. I seem to recall that there is a way to get a more accurate centroid, but I haven’t found a simple algorithm for doing so.

numpy.meshgrid — NumPy v2.1 ManualReturn a tuple of coordinate matrices from coordinate vectors. Make N-D coordinate arrays for vectorized evaluations of N-D scalar/vector fields over N-D grids, given one-dimensional coordinate arrays x1, x2,…, xn. Changed in version 1.9: 1-D and 0-D cases are allowed.

The N-dimensional array (ndarray) — NumPy v1.13 Manual - SciPy.orgAn ndarray is a (usually fixed-size) multidimensional container of items of the same type and size. The number of dimensions and items in an array is defined by its shape, which is a tuple of N positive integers that specify the sizes of each dimension.
