Python index_to_slice Examples

Example #1

    def get_index(matrix, constraints, row, col):
        """Returns a canonicalized index into a matrix.

        Parameters
        ----------
        matrix : LinOp
            The matrix to be indexed.
        constraints : list
            A list of constraints to append to.
        row : int
            The row index.
        col : int
            The column index.
        """
