discretize.utils.kron3#
- discretize.utils.kron3(A, B, C)[source]#
Compute kronecker products between 3 sparse matricies.
Where \(\otimes\) denotes the Kronecker product and A, B and C are sparse matrices, this function outputs \((A \otimes B) \otimes C\).
- Parameters:
- A, B, C
scipy.sparse.spmatrix Sparse matrices.
- A, B, C
- Returns:
scipy.sparse.csr_matrixKroneker between the 3 sparse matrices.
