The Khatri-Rao product of two matrices
Description
The function krp(A,B) returns the Khatri-Rao product of two matrices A and B, of
dimensions I x K and J x K respectively. The result is an IJ x K matrix formed by the matching
column-wise Kronecker products, i.e. the k-th column of the Khatri-Rao product is
defined as kronecker(A[, k], B[, k]).
Usage
krp(A, B)
Arguments
A
Matrix of order I x K.
B
Matrix of order J x K.
Value
The IJ x K matrix of columnwise Kronecker products.
