# Function kron Calculates the kronecker product of 2 matrices or vectors. NOTE: If a one dimensional vector / matrix is given, it will be wrapped so its two dimensions. See the examples. ## Syntax ```js math.kron(x, y) ``` ### Parameters Parameter | Type | Description --------- | ---- | ----------- `x` | Array | Matrix | First vector `y` | Array | Matrix | Second vector ### Returns Type | Description ---- | ----------- Array | Matrix | Returns the kronecker product of `x` and `y` ### Throws Type | Description ---- | ----------- ## Examples ```js math.kron([[1, 0], [0, 1]], [[1, 2], [3, 4]]) // returns [ [ 1, 2, 0, 0 ], [ 3, 4, 0, 0 ], [ 0, 0, 1, 2 ], [ 0, 0, 3, 4 ] ] math.kron([1,1], [2,3,4]) // returns [ [ 2, 3, 4, 2, 3, 4 ] ] ``` ## See also [multiply](multiply.md), [dot](dot.md), [cross](cross.md)
