squarenet.utils.dualgrid(grid, xp, N, IJ, D)[source]

squarenet.utils.dualgridflat(grid, xp, N)[source]

squarenet.utils.fill_in(data, stencil, fill_rank, xp)[source]

squarenet.utils.index_identity(shape)[source]: index_identy[i, j, k, …] = [i, j, k, …]

squarenet.utils.make_stencil(gridshape, dtype=<class 'float'>)[source]

Create a grid stencil ordered by distance to the center of the grid. This is a helper for embedding an arbitrary set of n_target points into a smooth convex subset of a hyperrectangular lattice.

Invalid positions are initialized with signed infinities, while valid positions can later be filled with the input data according to fill_rank.

Parameters:

gridshape (tuple of int) – The shape of the target grid.
dtype (data-type, optional) – The desired data-type for the stencil array (default is float).

Returns:

stencil (ndarray of shape (n, d)) – A stencil prefilled with signed infinity at forbidden positions.
fill_rank (ndarray of shape (n,)) – Ranking of the lattice points by increasing distance to the grid center. The positions satisfying fill_rank < n_target are the locations where the first n_target points should be inserted.

squarenet.utils.warn()

Issue a warning, or maybe ignore it or raise an exception.

message: Text of the warning message.
category: The Warning category subclass. Defaults to UserWarning.
stacklevel: How far up the call stack to make this warning appear. A value of 2 for example attributes the warning to the caller of the code calling warn().
source: If supplied, the destroyed object which emitted a ResourceWarning
skip_file_prefixes: An optional tuple of module filename prefixes indicating frames to skip during stacklevel computations for stack frame attribution.
