gridsmooth(Z, span)	Smooths values on 2D rectangular grid
meshsmooth(v, mesh, span)	Smooths values on 2D unstructured mesh
mesh2grid(v, mesh)	Interpolates from an unstructured coordinates (mesh) to a structured
grid2mesh(V, grid, mesh)	Interpolates from structured coordinates (grid) to unstructured

Module Contents

seisflows.tools.array.sortrows(a, return_index=False, return_inverse=False)

Sorts the rows of a numpy array. By default returns only the sorted array

Parameters:

• a (np.array) – array to sort

• return_index (bool) – return the indices and the sorted array

• return_inverse (bool) – returns the inverse sorted array as well

seisflows.tools.array.uniquerows(a, sort_array=False, return_index=False)

Finds unique rows of numpy array

Parameters:

• a (np.array) – array to find rows of

• sort_array (bool) – sort the rows before findingunique rows

• return_index (bool) – return indices as well as the unique rows

seisflows.tools.array.gridsmooth(Z, span)

Smooths values on 2D rectangular grid

Note:

‘grid’: set of structured coordinates, ‘mesh’: set of unstructured coordinates

Parameters:

• Z (np.array) – array to smooth

• span (float) – span to smooth along

Return type:

np.array

Returns:

smoothed array

seisflows.tools.array.meshsmooth(v, mesh, span)

Smooths values on 2D unstructured mesh

Note:

‘grid’: set of structured coordinates, ‘mesh’: set of unstructured coordinates

seisflows.tools.array.mesh2grid(v, mesh)

Interpolates from an unstructured coordinates (mesh) to a structured coordinates (grid)

seisflows.tools.array.grid2mesh(V, grid, mesh)

Interpolates from structured coordinates (grid) to unstructured coordinates (mesh)
