search geometric data for neighbours, or find nonzero entries of numeric data.

Syntax

indices, distances = find(grid, query)

Description

For an MTEX object, find(x, …) calls x.find(…). Additional positional and keyword arguments are passed to that method unchanged. Its documentation specifies the accepted inputs, units, symmetry handling and optional outputs. Consult the corresponding method for the behaviour of a particular object type.

For numeric arrays without an MTEX method, this calls numpy.flatnonzero.

Signature

find(x, *args, **kwargs)

Methods it calls

fibonacciS2Grid	the nearest grid point of every direction and its angle, or with eps the sparse matrices of the points within eps and their angles
orientation	the orientations of ori nearest to w up to symmetry, MATLAB’s orientation.find
S2Grid	the nearest grid point of every direction and its angle, or with eps the sparse matrices of the points within eps and their angles
SO3FibonacciGrid	the nearest grid rotation of every orientation, or the k nearest, or all within a radius, up to the symmetries of the grid’s frames
SO3Grid	the nearest grid rotation of every orientation, or the k nearest, or all within a radius, up to the symmetries of the grid’s frames
vector3d	the closest points of this list to others, the k closest, or all within a radius
