scipy.sparse.linalg.LaplacianNd.
tosparse
- 
LaplacianNd.tosparse()[source]
- Constructs a sparse array from the Laplacian data. The returned sparse
array format is dependent on the selected boundary conditions. - 
- Returns:
- 
- Lscipy.sparse.sparray
- The shape is - (N, N)where- N = np.prod(grid_shape).
