kron

kron(A, B)

Kronecker tensor product of two vectors or two matrices.

Examples

julia> A = [1 2; 3 4];
julia> B = [5 6; 7 8];
julia> kron(A, B)
4×4 Array{Int64,2}:
  5   6   10  12
  7   8   14  16
 15  18   20  24
 21  24   28  32

In this example, kron is used to compute the Kronecker tensor product of matrices A and B.

julia> x = [1, 2, 3];
julia> y = [4, 5, 6];
julia> kron(x, y)
9-element Array{Int64,1}:
  4
  5
  6
  8
 10

 18

Here, kron is used to compute the Kronecker tensor product of vectors x and y.

Common mistake example:

julia> A = [1 2; 3 4];
julia> B = [5, 6, 7, 8];
julia> kron(A, B)
ERROR: DimensionMismatch("inputs to kron must be vectors or matrices")

In this example, the inputs to kron are not valid. The function requires both inputs to be either vectors or matrices. Ensure that the inputs are of the correct dimensions and type.
