quantecon.ce_util.ckron(*arrays)[source]

Repeatedly applies the np.kron function to an arbitrary number of input arrays

Parameters: *arrays : tuple/list of np.ndarray out : np.ndarray The result of repeated kronecker products.

quantecon.ce_util.gridmake(*arrays)[source]

Expands one or more vectors (or matrices) into a matrix where rows span the cartesian product of combinations of the input arrays. Each column of the input arrays will correspond to one column of the output matrix.

Parameters: *arrays : tuple/list of np.ndarray Tuple/list of vectors to be expanded. out : np.ndarray The cartesian product of combinations of the input arrays.
