gustaf.utils.arr

gustaf/gustaf/utils/arr.py.

Useful functions for array / point operations. Named arr, since array is python library and it sounds funny.

Functions

bounds(arr)	Return bounds.
bounds_diagonal(arr)	Returns diagonal vector of the bounds.
bounds_mean(arr)	Returns mean of the bounds.
bounds_norm(arr)	Returns norm of the bounds.
close_rows(arr[, tolerance, ...])	Similar to unique_rows, but if data type is floats, use this one.
cross3d(a, b)	Cross product for two 3D arrays.
derivatives_to_normals(derivatives[, normalize])
enforce_len(value, n_len)	Given int, float, np.ndarray, tuple, list, returns an array with n_len len().
is_one_of_shapes(arr, shapes[, strict])	Tuple/list of given shapes, iterates and checks with is_shape.
is_shape(arr, shape[, strict])	Checks if arr matches given shape.
make_c_contiguous(array[, dtype])	Make given array like object a c contiguous np.ndarray.
rotate(arr, rotation[, rotation_axis, degree])	Rotates given arrays.
rotation_matrix(rotation[, degree])	Compute rotation matrix.
rotation_matrix_around_axis([axis, ...])	Compute rotation matrix given the axis of rotation.
select_with_ranges(arr, ranges)	Select array with ranges of each column.
unique_rows(in_arr[, return_index, ...])	Find unique rows using np.unique, but apply tricks.
