vectors

Utils for operating on 2D Diffraction Patterns.

Functions

detector_to_fourier(k_xy, wavelength, ...)	Maps two-dimensional Cartesian coordinates in the detector plane to three-dimensional coordinates in reciprocal space, with origo in [000].
calculate_norms(z)	Calculates the norm of an array of cartesian vectors.
calculate_norms_ragged(z)	Calculates the norm of an array of cartesian vectors.
filter_vectors_ragged(z, min_magnitude, ...)	Filters the diffraction vectors to accept only those with magnitudes within a user specified range.
filter_vectors_edge_ragged(z, x_threshold, ...)	Filters the diffraction vectors to accept only those not within a user specified proximity to detector edge.
normalize_or_zero(v)	Normalize v, or return the vector directly if it has zero length.
get_rotation_matrix_between_vectors(from_v1, ...)	Calculates the rotation matrix from one pair of vectors to the other.
get_npeaks(found_peaks)	Returns the number of entries in a list.
get_angle_cartesian_vec(a, b)	Compute the angles between two lists of vectors in a cartesian coordinate system.
get_angle_cartesian(a, b)	Compute the angle between two vectors in a cartesian coordinate system.
filter_vectors_near_basis(vectors, basis[, ...])	Filter an array of vectors to only the list of closest vectors to some set of basis vectors.
vectors_to_polar(vectors[, columns])	Converts a list of vectors to polar coordinates.
to_cart_three_angles(vectors)
polar_to_cartesian(vectors)
get_vectors_mesh(g1_norm, g2_norm, g_norm_max)	Calculate vectors coordinates of a mesh defined by a norm, a rotation and a shear component.
get_angles(angles)	This function takes a list of angles and returns the angles between each pair of angles.
get_filtered_combinations(pks, num[, ...])	Creates combinations of num peaks but forces at least one of the combinations to have an intensity higher than the intensity_threshold.
convert_to_markers(peaks, signal)	Convert a set of (flattened) peaks to a set of markers for plotting.
points_to_polygon(points[, num_points])	Convert a set of points to a polygon by creating a polygon.
points_to_poly_collection(points[, hull_index])	Convert a set of points to a polygon collection by creating a polygon.
column_mean(vectors, columns)	Calculate the mean of the columns of a set of vectors.
vectors2image(vectors, image_size, scales, ...)	Convert a set of vectors to an image by binning the vectors into a 2D histogram.
get_three_angles(pks[, k_index, ...])	This function takes the angle between three points and determines the angle between them, returning the angle if it is repeated using the accept_threshold to measure the acceptable difference between angle a and angle b.
